AD5933应用
阻抗测量芯片AD5933原理及其应用时间：2010-03-04 23:48:25 来源：作者：1 AD5933芯片概述1.1 主要性能AD5933是一款高精度的阻抗测量芯片，内部集成了带有12位，采样率高达1MSPS的AD转换器的频率发生器。
这个频率发生器可以产生特定的频率来激励外部电阻，电阻上得到的响应信号被ADC采样，并通过片上的DSP进行离散的傅立叶变换。
傅立叶变换后返回在这个输出频率下得到的实部值R和虚部值I。
这样就可以很容易的计算出在每个扫描频率下的傅立叶变换的模和电阻的相角。
其中模＝，相角＝。
AD5933主要具有以下特性：λ可编程的频率发生器，最高频率可达100KHzλ作为设备通过口和主机通讯，实现频率扫面控制λ频率分辨率为27位（<0.1Hz）λ阻抗测量范围为100Ω到10MΩλ内部带有温度传感器，测量误差范围为±2℃λ带有内部时钟λ可以实现相位测量λ系统精度为0.5%λ可供选择的电源范围为2.7V到5Vλ正常工作的温度范围-40℃到+125℃λ 16脚SSOP封装1.2 AD5933的引脚定义图1给出了AD5933的封装图，表1给出了AD5933的引脚定义。

AD5243VFigure 2. AD5248GENERAL DESCRIPTIONThe AD5243 and AD5248 provide a compact 3 mm × 4.9 mm packaged solution for dual 256-position adjustment applica-tions. These devices perform the same electronic adjustment function as a 3-terminal mechanical potentiometer (AD5243) or a 2-terminal variable resistor (AD5248). Available in four different end-to-end resistance values (2.5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ), these low temperature coefficient devices are ideal for high accuracy and stability variable resistance adjustments. The wiper settings are controllable through the I2C compatible digital interface. The AD5248 has extra package address decode pins AD0 and AD1, allowing multiple parts to share the same I2C 2-wire bus on a PCB. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.1Operating from a 2.7 V to 5.5 V power supply and consuming less than 6 µA allows for usage in portable battery-operated applications.For applications that program the AD5243/AD5258 at the factory, Analog Devices offers device programming software running on Windows® NT/2000/XP operating systems. This software effectively replaces any external I2C controllers, which in turn enhances users’ systems time-to-market. An AD5243/ AD5248 evaluation kit and software are available. The kit includes a cable and instruction manual.1The terms digital potentiometer, VR, and RDAC are used interchangeably.AD5243/AD5248Rev. 0 | Page 2 of 20TABLE OF CONTENTSElectrical Characteristics—2.5 kΩ Version...................................3 Electrical Characteristics—10 kΩ, 50 kΩ, 100 kΩ Versions.......4 Timing Characteristics—All Versions...........................................5 Absolute Maximum Ratings............................................................6 ESD Caution..................................................................................6 Pin Configurations and Function Descriptions...........................7 Typical Performance Characteristics.............................................8 Test Circuits.....................................................................................12 Theory of Operation......................................................................13 Programming the Variable Resistor and Voltage....................13 Programming the Potentiometer Divider...............................14 ESD Protection...........................................................................14 Terminal Voltage Operating Range..........................................14 Power-Up Sequence...................................................................14 Layout and Power Supply Bypassing.......................................14 Constant Bias to Retain Resistance Setting.............................15 Evaluation Board........................................................................15 I 2C Interface....................................................................................16 I 2C Compatible 2-Wire Serial Bus...........................................16 Outline Dimensions.......................................................................19 Ordering Guide..

R-DNL measures the relative step change from ideal between successive tap positions. Parts are guaranteed monotonic. 3V AB = V DD , wiper (VW) = no connect. 4INL and DNL are measured at V W with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. V A = V DD and V B = 0 V. DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions. 5Resistor terminals A, B, W have no limitations on polarity with respect to each other. 6Guaranteed by design and not subject to production test. 7Measured at the A terminal. The A terminal is open circuited in shutdown mode. 8P DISS is calculated from (I DD × V DD ). CMOS logic level inputs result in minimum power dissipation. 9All dynamic characteristics use V DD = 5 V. 10See timing diagrams for locations of measured values. 11The maximum t HD:DAT must be met only if the device does not stretch the low period (t LOW ) of the SCL signal.AD5243/AD5248Rev. 0 | Page 6 of 20ABSOLUTE MAXIMUM RATINGST A = 25°C, unless otherwise noted.Table 4.Parameter ValueV DD to GND–0.3 V to +7 V V A , V B , V W to GNDV DD Terminal Current, Ax to Bx, Ax to Wx, Bx to Wx 1Pulsed±20 mA Continuous±5 mA Digital Inputs and Output Voltage to GND 0 V to 7 VOperating Temperature Range–40°C to +125°C Maximum Junction Temperature (T JMAX ) 150°CStorage Temperature–65°C to +150°C Lead Temperature (Soldering, 10 sec) 300°C Thermal Resistance 2 θJA : MSOP-10230°C/W1Maximum terminal current is bounded by the maximum current handling of the switches, maximum power dissipation of the package, and maximum applied voltage across any two of the A, B, and W terminals at a given resistance. 2Package power dissipation = (T JMAX − T A )/θJA .Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operationalsection of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.ESD CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performancedegradation or loss of functionality.AD5243/AD5248Rev. 0 | Page 7 of 20PIN CONFIGURATIONS AND FUNCTION DESCRIPTIONSB1A1W2W1B2A2SDA GND SCLV DD 04109-0-027Figure 3.

Test Circuit for Common-Mode Leakage CurrentAD5243/AD5248THEORY OF OPERATIONThe AD5243/AD5248 are 256-position digitally controlled variable resistor (VR) devices.An internal power-on preset places the wiper at midscaleduring power-on, which simplifies the fault condition recovery at power-up.PROGRAMMING THE VARIABLE RESISTOR AND VOLTAGERheostat OperationThe nominal resistance of the RDAC between Terminals A and B is available in 2.5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ. The nominal resistance (R AB ) of the VR has 256 contact points accessed by the wiper terminal, plus the B terminal contact. The 8-bit datain the RDAC latch is decoded to select one of the 256 possible settings.04109-0-012Figure 36. Rheostat Mode ConfigurationAssuming that a 10 kΩ part is used, the wiper’s first connection starts at the B terminal for data 0x00. Because there is a 50 Ω wiper contact resistance, such a connection yields a minimum of 100 Ω (2 × 50 Ω) resistance between Terminals W and B. The second connection is the first tap point, which corresponds to 139 Ω (R WB = R AB /256 + 2 × R W = 39 Ω + 2 × 50 Ω) for data 0x01. The third connection is the next tap point, representing 178 Ω (2 × 39 Ω + 2 × 50 Ω) for data 0x02, and so on. Each LSB data value increase moves the wiper up the resistor ladder until the last tap point is reached at 10,100 Ω (R AB + 2 × R W ).04109-0-013Figure 37. AD5243 Equivalent RDAC CircuitThe general equation determining the digitally programmed output resistance between W and B isW AB WB R R DD R ×+×=2256)((1) where:D is the decimal equivalent of the binary code loaded in the 8-bit RDAC register.R AB is the end-to-end resistance.R W is the wiper resistance contributed by the on resistance of the internal switch.In summary, if R AB = 10 kΩ and the A terminal is open circuited, the following output resistance R WB is set for the indicated RDAC latch codes.Table 7. Codes and Corresponding R WB ResistanceD (Dec) R WB (Ω) Output State255 9,961 Full scale (R AB − 1 LSB + R W ) 128 5,060 Midscale 1 139 1 LSB100Zero scale (wiper contact resistance)Note that, in the zero-scale condition, a finite wiper resistance of 100 Ω is present. Care should be taken to limit the current flow between W and B in this state to a maximum pulse current of no more than 20 mA. Otherwise, degradation or possible destruction of the internal switch contact can occur.Similar to the mechanical potentiometer, the resistance of the RDAC between the Wiper W and Terminal A also produces a digitally controlled complementary resistance, R W A . When these terminals are used, the B terminal can be opened. Setting the resistance value for R W A starts at a maximum value of resistance and decreases as the data loaded in the latch increases in value. The general equation for this operation isW AB WA R R DD R ×+×−=2256256)( (2) For R AB = 10 kΩ and the B terminal open circuited, thefollowing output resistance R W A is set for the indicated RDAC latch codes.Table 8. Codes and Corresponding R WA ResistanceD (Dec) R WA (Ω) Output State 255 139 Full scale 128 5,060 Midscale 1 9,961 1 LSB 010,060 Zero scaleAD5243/AD5248Typical device-to-device matching is process lot dependent and may vary by up to ±30%. Because the resistance element is processed in thin film technology, the change in R AB withtemperature has a very low 35 ppm/°C temperature coefficient.PROGRAMMING THE POTENTIOMETER DIVIDERVoltage Output OperationThe digital potentiometer easily generates a voltage divider at wiper-to-B and wiper-to-A proportional to the input voltage at A to B. Unlike the polarity of V DD to GND, which must be positive, voltage across A to B, W to A, and W to B can be at either polarity.04109-0-014Figure 38. Potentiometer Mode ConfigurationIf ignoring the effect of the wiper resistance for approximation, connecting the A terminal to 5 V and the B terminal to ground produces an output voltage at the wiper-to-B starting at 0 V up to 1 LSB less than 5 V . Each LSB of voltage is equal to the volt-age applied across terminal AB divided by the 256 positions of the potentiometer divider. The general equation defining the output voltage at V W with respect to ground for any valid input voltage applied to terminals A and B isB A W DV D D V 256256256)(−+=(3) A more accurate calculation, which includes the effect of wiper resistance, V W , isB ABWA A AB WB W V R D R V R D R D V )()()(+=(4) Operation of the digital potentiometer in the divider moderesults in a more accurate operation overtemperature. Unlike the rheostat mode, the output voltage is dependent mainly on the ratio of the internal resistors R W A and R WB and not the absolute values. Therefore, the temperature drift reduces to 15 ppm/°C.ESD PROTECTIONAll digital inputs are protected with a series of input resistors and parallel Zener ESD structures, shown in Figure 39 and Figure 40. This applies to the digital input pins SDA, SCL, AD0, and AD1 (AD5248 only).04109-0-015Figure 39. ESD Protection of Digital Pins04109-0-016Figure 40. ESD Protection of Resistor TerminalsTERMINAL VOLTAGE OPERATING RANGEThe AD5243/AD5248 V DD and GND power supply defines the boundary conditions for proper 3-terminal digital potentiome-ter operation. Supply signals present on Terminals A, B, and W that exceed V DD or GND are clamped by the internal forwardbiased diodes (see Figure 41).GNDA W BV DD04109-0-017Figure 41. Maximum Terminal Voltages Set by V DD and GNDPOWER-UP SEQUENCEBecause the ESD protection diodes limit the voltage complianceat Terminals A, B, and W (see Figure 41), it is important topower V DD /GND before applying any voltage to Terminals A, B, and W; otherwise, the diode is forward biased such that V DD is powered unintentionally and may affect the rest of the user’s circuit. The ideal power-up sequence is in the following order: GND, V DD , digital inputs, and then V A , V B , and V W . The relative order of powering V A , V B , V W , and the digital inputs is not important as long as they are powered after V DD /GND.LAYOUT AND POWER SUPPLY BYPASSINGIt is good practice to employ compact, minimum lead length layout design. The leads to the inputs should be as direct as possible with a minimum conductor length. Ground paths should have low resistance and low inductance.Similarly, it is also good practice to bypass the power supplies with quality capacitors for optimum stability. Supply leads to the device should be bypassed with disk or chip ceramic capacitors of 0.01 µF to 0.1 µF. Low ESR 1 µF to 10 µF tantalum or electro-lytic capacitors should also be applied at the supplies tominimize any transient disturbance and low frequency ripple (see Figure 42). Note that the digital ground should also be joined remotely to the analog ground at one point to minimize the ground bounce.AD5243/AD5248V 04109-0-018Figure 42. Power Supply BypassingCONSTANT BIAS TO RETAIN RESISTANCE SETTINGFor users who desire nonvolatility but cannot justify the addi-tional cost for the EEMEM, the AD5243/AD5248 may be considered as low cost alternatives by maintaining a constant bias to retain the wiper setting. The AD5243/AD5248 aredesigned specifically with low power in mind, which allows low power consumption even in battery-operated systems. Thegraph in Figure 43 demonstrates the power consumption from a 3.4 V 450 mAhr Li-Ion cell phone battery, which is connected to the AD5243/AD5248. The measurement over time shows that the device draws approximately 1.3 µA and consumes negligible power. Over a course of 30 days, the battery is depleted by less than 2%, the majority of which is due to the intrinsic leakage current of the battery itself.DAYSB A T T E R Y L I F E D E P L E T E D90%92%94%96%5101598%100%20253004109-0-019Figure 43. Battery Operating Life DepletionThis demonstrates that constantly biasing the potentiometer is not an impractical approach. Most portable devices do not require the removal of batteries for the purpose of charging. Although the resistance setting of the AD5243/AD5248 is lost when the battery needs replacement, such events occur rather infrequently such that this inconvenience is justified by the lower cost and smaller size offered by the AD5243/AD5248. If and when total power is lost, the user should be provided with a means to adjust the setting accordingly.EVALUATION BOARDAn evaluation board, along with all necessary software, is avail-able to program the AD5243/AD5248 from any PC running Windows 98/2000/XP . The graphical user interface, as shown in Figure 44, is straightforward and easy to use. More detailed information is available in the user manual, which comes with the board.Figure 44. AD5243 Evaluation Board SoftwareThe AD5243/AD5248 start at midscale upon power-up. To increment or decrement the resistance, the user may simply move the scrollbars on the left. To write any specific value, the user should use the bit pattern in the upper screen and press the Run button. The format of writing data to the device is shown in Table 9. To read the data out from the device, the user can simply press the Read button. The format of the read bits is shown in Table 10.。

The new benefits are:E VEN Q UIETER R UNNINGA brand-new quiet compressor has been fitted to almost eliminate any of the operating noise level from the unit.R EDUCED AND I MPROVED M AINTENANCEThe new compressor has significantly improved maintenance intervals due to the new and better quality lifetime of the compressor components. The new compressor design means that service parts can be changed extremely easily and quickly without the need to remove the compressor.A new internal pipe work design has been fitted to improve the lifetime of some of the components. BEFORE STARTINGMake sure any transit material inside the AD51 has been removed before switching on. It may also be necessary to plug the compressor back in inside the unit.MODE OF OPERATIONThis stand-alone unit draws in atmospheric air and converts it to dry air. The dry air has a dewpoint of better than -60°C and a variable flowrate up to a maximum of 25 litres/minute.The AD51 Flow Scheme (Fig 1) shows the air is compressed to 3.5 bar pressure and passed, via a particle filter, to a factory-sealed, twin-column pressure-swing adsorption dryer. An oil-free compressor is employed to avoid contamination of the molecular sieve drying agent by lubricating oil.At any one time, pressurised air is dried by passing it up one of the columns. Simultaneously, a fraction of this dry air is bled back down the other column at low pressure to purge it of water vapour. After a pre-set time, the action of the two columns is reversed by means of electrically operated change over valves.The pressurised dry air passes through a filter/regulator to remove pressure pulses during column switching and limit the maximum output pressure. The output flowrate is controlled by the user with a built-in needle valve and flowmeter.MAINTENANCE AND TROUBLE SHOOTINGThe AD51 is designed to be a low-maintenance unit. A useful indication that the unit is functioning correctly is that a brief hiss can be heard at regular (one minute) intervals as the air valves switch the action of the columns.When the AD51 is used with the Cryostream Cooler to provide the dry air shroud for the nitrogen gas stream, a deterioration in the dryness of the dry air will show up as frost forming evenly all around the cold nitrogen stream delivery nozzle.P RECAUTIONSIf you have not used the AD51 for some time it may be necessary to run the unit overnight to dry down the columns.R OUTINE MAINTENANCEThe AD51 is designed to run for more than 15,000 hours before needing any maintenance. However, local conditions may accelerate wear of components or clogging of filters. Routine or preventative maintenance may be carried out by users, utilising a qualified technician. The following items may require attention.Compressor Delivery FilterEventually the Compressor Delivery Filter will become clogged with the finer particles of room dirt and the wear products from the compressor. This large capacity filter element is designed to last 15,000 hours and should normally be replaced at the same time as the compressor is serviced. Do not be surprised if the filter element is wet – the compressed air has not been dried at this point.For details of the filter replacement see Appendix 3.CompressorAt some stage (usually longer than 15,000 hours) the carbon impregnated plastic cup seal in the compressor will wear out. The eventual failure of the cup seal is a very sudden process and the dryness of the dry air will deteriorate rapidly, also the maximum flowrate of dry air will drop below 25 litres/minute (perhaps less than 10 litres/minute).This situation requires the compressor to be serviced.C HECKING THE DRY AIR OUTPUTNote: Make sure to run the AD51 overnight before checking the dry air output, this will give the drying columns a chance to dry down.The residual water vapour content of the AD51 dry air output may be measured with a suitable hygrometer calibrated down to -70°C dewpoint. Allow at least 10 minutes for the reading to reach equilibrium.F AULTSNote: If any trips are activated the cause should be determined, preferably by a qualified technician, before restarting the unit.A rear panel fuse (T1A, 220-240V or T2A, 100-115V) protects the transformer that drives the power supply, control board, indicator lamps, cooling fan and solenoid valves.A fuse (T2A) mounted internally on the control board protects the low voltage supply to the control logic circuits.A rear panel circuit breaker operates if the compressor draws excessive current – push the black button in to reset.A manual reset thermal switch operates if the temperature inside the quiet box rises excessively for any reason. If an overheat occurs the HOT! lamp will flash until the thermal switch is reset. The thermal switch is mounted in the compressor compartment (see Fig 4 (M)) - press the red button to reset.FACTORY OVERHAUL/SERVICEAfter extended running you may consider it desirable for the AD51 to have a complete factory service and full recommissioning procedure. Please contact your agent or Oxford Cryosystems to discuss this type of service if required.LIST OF APPENDICESA PPENDIX 1 General Circuit DiagramA PPENDIX 2 Control Board Circuit DiagramA PPENDIX 3 Compressor Delivery Filter ReplacementAPPENDIX 1 - GENERAL CIRCUIT DIAGRAMAPPENDIX 2 - CONTROL BOARD CIRCUIT DIAGRAMAPPENDIX3 - COMPRESSOR DELIVERY FILTER REPLACEMENT1.Switch off the AD51 and disconnect the electrical power.2.Remove the AD51 top cover by lifting the four white plastic plugs and unscrewing the four M5socket caphead screws with the 4mmA/F hexagon balldriver provided.3.The Compressor Delivery Filter (A) is a square grey unit mounted just under the top cover nearthe control panel end of the AD51.

B–4–AD22103THEORY OF OPERATIONThe AD22103 is a ratiometric temperature sensor IC whose output voltage is proportional to power supply voltage. The heart of the sensor is a proprietary temperature-dependent resis-tor, similar to an RTD, which is built into the IC. Figure 4shows a simplified block diagram of the AD22103.+VV OUTFigure 4.Simplified Block DiagramThe temperature-dependent resistor, labeled R T , exhibits a change in resistance that is nearly linearly proportional to tem-perature. This resistor is excited with a current source that is proportional to power supply voltage. The resulting voltage across R T is therefore both supply voltage proportional and lin-early varying with temperature. The remainder of the AD22103consists of an op amp signal conditioning block that takes the voltage across R T and applies the proper gain and offset to achieve the following output voltage function:V OUT = (V S /3.3V ) × [0.25V + (28.0mV /°C ) × T A ]ABSOLUTE ACCURACY AND NONLINEARITY SPECIFICATIONSFigure 5 graphically depicts the guaranteed limits of accuracy for the AD22103 and shows the performance of a typical part.As the output is very linear, the major sources of error are offset,i.e., error at room temperature, and span error, i.e., deviation from the theoretical 28.0mV/°C. Demanding applications can achieve improved performance by calibrating these offset and gain errors so that only the residual nonlinearity remains as a source of error.E R R O R – °CTEMPERATURE – °C2.5–2.52.00–0.5–1.0–2.01.50.5010050–1.51.0V S = 3.6V V S = 3.3V V S = 2.7VFigure 5.Typical AD22103 PerformanceOUTPUT STAGE CONSIDERATIONSAs previously stated, the AD22103 is a voltage output device. A basic understanding of the nature of its output stage is useful for proper application. Note that at the nominal supply voltage of 3.3 V, the output voltage extends from 0.25V at 0°C to +3.05V at +100°C. Furthermore, the AD22103 output pin is capable of withstanding an indefinite short circuit to either ground or the power supply. These characteristics are provided by the output stage structure shown in Figure 6.OUTV SFigure 6.Output Stage StructureThe active portion of the output stage is a PNP transistor with its emitter connected to the V S supply and collector connected to the output node. This PNP transistor sources the required amount of output current. A limited pull-down capability is provided by a fixed current sink of about –100µA. (Here,“fixed” means the current sink is fairly insensitive to either sup-ply voltage or output loading conditions. The current sink ca-pability is a function of temperature, increasing its pull-down capability at lower temperatures.)Due to its limited current sinking ability, the AD22103 is inca-pable of driving loads to the V S power supply and is instead in-tended to drive grounded loads. A typical value for short circuit current limit is 7mA, so devices can reliably source 1mA or 2mA. However, for best output voltage accuracy and minimal internal self-heating, output current should be kept below 1mA.Loads connected to the V S power supply should be avoided as the current sinking capability of the AD22103 is very limited.These considerations are typically not a problem when driving a microcontroller analog to digital converter input pin (see MICROPROCESSOR A/D INTERFACE ISSUES).MOUNTING CONSIDERATIONSIf the AD22103 is thermally attached and properly protected, it can be used in any measuring situation where the maximum range of temperatures encountered is between 0°C and +100°C.Because plastic IC packaging technology is employed, excessive mechanical stress must be avoided when fastening the device with a clamp or screw-on heat tab. Thermally conductive epoxy or glue is recommended for typical mounting conditions. In wet or corrosive environments, an electrically isolated metal or ce-ramic well should be used to shield the AD22103. Because the part has a voltage output (as opposed to current), it offers mod-est immunity to leakage errors, such as those caused by conden-sation at low temperatures.AD22103REV. B –5–THERMAL ENVIRONMENT EFFECTSThe thermal environment in which the AD22103 is used deter-mines two performance traits: the effect of self-heating on accu-racy and the response time of the sensor to rapid changes in temperature. In the first case, a rise in the IC junction tempera-ture above the ambient temperature is a function of two variables;the power consumption of the AD22103 and the thermal resis-tance between the chip and the ambient environment θJA . Self-heating error in degrees Celsius can be derived by multiplying the power dissipation by θJA. Because errors of this type can vary widely for surroundings with different heat sinking capacities, it is necessary to specify θJA under several conditions. Table I shows how the magnitude of self-heating error varies relative to the environment. A typical part will dissipate about 1.5mW at room temperature with a 3.3V supply and negligible output loading. In still air, without a “heat sink,” the table below indi-cates a θJA of 190°C/W, yielding a temperature rise of 0.285°C.Thermal rise will be considerably less in either moving air or with direct physical connection to a solid (or liquid) body.Table I.Thermal Resistance (TO-92)MediumθJA (°C/Watt)τ (sec)*Aluminum Block 602Moving Air**Without Heat Sink 75 3.5Still AirWithout Heat Sink19015*The time constant τ is defined as the time to reach 63.2% of the final temperature change.**1200 CFM.Response of the AD22103 output to abrupt changes in ambient temperature can be modeled by a single time constant τ expo-nential function. Figure 7 shows typical response time plots for a few media of interest.TIME – sec1005009060201080703040010010% O F F I N A L V A L U E S2030405060708090Figure 7.Response TimeThe time constant τ is dependent on θJA and the specific heat capacities of the chip and the package. Table I lists the effec-tive τ (time to reach 63.2% of the final value) for a few different media. Copper printed circuit board connections wereneglected in the analysis; however, they will sink or conduct heat directly through the AD22103’s solder plated copper leads.When faster response is required, a thermally conductive grease or glue between the AD22103 and the surface temperature being measured should be used.MICROPROCESSOR A/D INTERFACE ISSUESThe AD22103 is especially well suited to providing a low cost temperature measurement capability for microprocessor/microcontroller based systems. Many inexpensive 8-bit micro-processors now offer an onboard 8-bit ADC capability at a mod-est cost premium. Total “cost of ownership” then becomes a function of the voltage reference and analog signal conditioning necessary to mate the analog sensor with the microprocessor ADC. The AD22103 can provide an ideal low cost system by eliminating the need for a precision voltage reference and any additional active components. The ratiometric nature of the AD22103 allows the microprocessor to use the same power sup-ply as its ADC reference. Variations of hundreds of millivolts in the supply voltage have little effect as both the AD22103 and the ADC use the supply as their reference. The nominal AD22103 signal range of 0.25 V to 3.05 V (0°C to +100°C)makes good use of the input range of a 0V to 3.3 V ADC. A single resistor and capacitor are recommended to provide im-munity to the high speed charge dump glitches seen at many microprocessor ADC inputs (see Figure 1).An 8-bit ADC with a reference of 3.3 V will have a least signifi-cant bit (LSB) size of 3.3 V/256 = 12.9 mV. This corresponds to a nominal resolution of about 0.46°C/bit.USE WITH A PRECISION REFERENCE AS THE SUPPLY VOLTAGEWhile the ratiometric nature of the AD22103 allows for system operation without a precision voltage reference, it can still be used in such systems. Overall system requirements involving other sensors or signal inputs may dictate the need for a fixed precision ADC reference. The AD22103 can be converted to absolute voltage operation by using a precision reference as the supply voltage. For example, a 3.3V reference can be used to power the AD22103 directly. Supply current will typically be 500µA which is usually within the output capability of the refer-ence. A large number of AD22103s may require an additional op amp buffer, as would scaling down a 10.00V reference that might be found in “instrumentation” ADCs typically operating from ±15V supplies.USING THE AD22103 WITH ALTERNATIVE SUPPLY VOLTAGESBecause of its ratiometric nature the AD22103 can be used at other supply voltages. Its nominal transfer function can be recal-culated based on the new supply voltage. For instance, if using the AD22103 at V S = 5 V the transfer function would be given by:V O =V S 5V 0.25V +28m V °C ×T A5V3.3V V O =V S 5V 0.378V +42.42mV°C×T AREV.

AD5203–SPECIFICATIONS
ELECTRICAL CHARACTERISTICS (VDD = +3 V ؎ 10% or +5 V ؎ 10%, VA = +VDD, VB = 0 V, –40؇C < TA < +85؇C unless otherwise noted)
GENERAL DESCRIPTION The AD5203 provides a quad channel, 64-position digitallycontrolled variable resistor (VR) device. These parts perform the same electronic adjustment function as a potentiometer or variable resistor. The AD5203 contains four independent variable resistors in a 24-lead SOIC and the compact TSSOP-24 packages. Each part contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digital code loaded into the controlling serial input register. The resistance between the wiper and either endpoint of the fixed resistor varies linearly with respect to the digital code transferred into the VR latch. Each variable resistor offers a completely programmable value of resistance, between the A terminal and the wiper or the B terminal and the wiper. The fixed A-to-B terminal resistance of 10 kΩ, or 100 kΩ has a ± 1% channel-tochannel matching tolerance with a nominal temperature coefficient of 700 ppm/°C.

However, no responsibility is assumed by Analog Devices for its use, nor for any infringements of patents or other rights of third parties which may result from its use. No license is granted by implication or otherwise under any patent or patent rights of Analog Devices.
Each VR has its own VR latch which holds its programmed resistance value. These VR latches are updated from an internal serial-to-parallel shift register that is loaded from a standard 3-wire serial-input digital interface. Eight data bits make up the data word clocked into the serial input register. The data word is decoded where the first two bits determine the address of the VR latch to be loaded, the last 6-bits are data. A serial data output pin at the opposite end of the serial register allows simple daisychaining in multiple VR applications without additional external decoding logic.

The reset RS pin forces the wiper to the midscale position by loading 20H into the VR latch. The SHDN pin forces the resistor to an end-to-end open circuit condition on terminal A and shorts the wiper to terminal B, achieving a microwatt power shutdown state. When shutdown is returned to logic-high the previous latch settings put the wiper in the same resistance setting prior to shutdown.
