The architecture is based on capacitive redistribution which inherently includes a sample/hold function. The converter is fabricated on a 0.6µs CMOS process.The basic operation of the ADS7843 is shown in Figure 1.The device requires an external reference and an external clock. It operates from a single supply of 2.7V to 5.25V. The external reference can be any voltage between 1V and +V CC .The value of the reference voltage directly sets the input range of the converter. The average reference input current depends on the conversion rate of the ADS7843.The analog input to the converter is provided via a four-channel multiplexer. A unique configuration of low on-resistance switches allows an unselected ADC input channel to provide power and an accompanying pin to provide ground for an external device. By maintaining a differenital input to the converter and a differential reference architecture, it is possible to negate the switch’s on-resistance error (should this be a source of error for the particular measurement).ANALOG INPUTFigure 2 shows a block diagram of the input multiplexer on the ADS7843, the differential input of the A/D converter, and the converter’s differential reference. Table I and Table II control bits and the configuration of the ADS7843. The control bits are provided serially via the DIN pin—see the Digital Interface section of this data sheet for more details.When the converter enters the hold mode, the voltage differ-ence between the +IN and –IN inputs (see Figure 2) is captured on the internal capacitor array. The input current on the analog inputs depends on the conversion rate of the device. During the sample period, the source must charge the internal sampling capacitor (typically 25pF). After the ca-pacitor has been fully charged, there is no further input current. The rate of charge transfer from the analog source to the converter is a function of conversion rate.FIGURE 1. Basic Operation of the ADS7843.®7ADS7843FIGURE 2. Simplified Diagram of Analog Input.REFERENCE INPUTThe voltage difference between +REF and –REF (see Figure 2) sets the analog input range. The ADS7843 will operate with a reference in the range of 1V to +V CC . There are several critical items concerning the reference input and its wide voltage range. As the reference voltage is reduced, the analog voltage weight of each digital output code is also reduced.This is often referred to as the LSB (least significant bit) size and is equal to the reference voltage divided by 4096. Any offset or gain error inherent in the A/D converter will appear to increase, in terms of LSB size, as the reference voltage is reduced. For example, if the offset of a given converter is 2LSBs with a 2.5V reference, it will typically be 5 LSBs with a 1V reference. In each case, the actual offset of the device is the same, 1.22mV. With a lower reference voltage, more care must be taken to provide a clean layout including adequate bypassing, a clean (low noise, low ripple) power supply, a low-noise reference, and a low-noise input signal.The voltage into the V REF input is not buffered and directly drives the capacitor digital-to-analog converter (CDAC) por-tion of the ADS7843. Typically, the input current is 13µA with V REF = 2.7V and f SAMPLE = 125kHz. This value will vary by a few microamps depending on the result of the conver-sion. The reference current diminishes directly with both conversion rate and reference voltage. As the current from the reference is drawn on each bit decision, clocking the con-verter more quickly during a given conversion period will not reduce overall current drain from the reference.There is also a critical item regarding the reference when making measurements where the switch drivers are on. For this discussion, it’s useful to consider the basic operation ofthe ADS7843 as shown in Figure 1. This particular appli-cation shows the device being used to digitize a resistive touch screen. A measurement of the current Y position of the pointing device is made by connecting the X+ input to the A/D converter, turning on the Y+ and Y– drivers, and digitizing the voltage on X+ (see Figure 3 for a block diagram). For this measurement, the resistance in the X+lead does not affect the conversion (it does affect the settling time, but the resistance is usually small enough that this is not a concern).FIGURE 3.Simplified Diagram of Single-Ended Reference(SER/DFR HIGH, Y Switches Enabled, X+ is Analog Input).®8ADS7843However, since the resistance between Y+ and Y– is fairly low, the on-resistance of the Y drivers does make a small difference. Under the situation outlined so far, it would not be possible to achieve a zero volt input or a full-scale input regardless of where the pointing device is on the touch screen because some voltage is lost across the internal switches. In addition, the internal switch resistance is un-likely to track the resistance of the touch screen, providing an additional source of error.complete conversion can be accomplished with three serial communications, for a total of 24 clock cycles on the DCLK input.The first eight clock cycles are used to provide the control byte via the DIN pin. When the converter has enough information about the following conversion to set the input multiplexer, switches, and reference inputs appropriately,the converter enters the acquisition (sample) mode and, if needed, the internal switches are turned on. After three more basic serial interface. Each communication between the pro-cessor and the converter consists of eight clock cycles. OneTABLE IV.Descriptions of the Control Bits within theControl Byte.®9ADS78431DCLKCS8111DOUT BUSYSDIN CONTROL BITSSCONTROL BITS109876543210111098118single-ended mode, the converter’s reference voltage is always the difference between the V REF and GND pins. In differential mode, the reference voltage is the difference between the currently enabled switches. See Tables I and II and Figures 2 through 4 for more information. The last two bits (PD1 - PD0) select the power- down mode as shown in Table V. If both inputs are HIGH, the device is always powered up. If both inputs are LOW, the device enters a power-down mode between conversions. When a new con-version is initiated, the device will resume normal operation instantly—no delay is needed to allow the device to power up and the very first conversion will be valid. There are two power-down modes: one where PENIRQ is disabled and one where it is enabled.PD1PD0PENIRQ DESCRIPTIONEnabledPower-down between conversions. When each conversion is finished, the converter enters a low power mode. At the start of the next conversion,the device instantly powers up to full power.There is no need for additional delays to assure full operation and the very first conversion is valid. The Y– switch is on while in power-down.01Disabled Same as mode 00, except PENIRQ is disabled.The Y– switch is off while in power-down mode.10Disabled Reserved for future use.11DisabledNo power-down between conversions, device is always powered.FIGURE 5.

No DCLK Delay Required with DedicatedSerial Port.®10ADS784316-Clocks per ConversionThe control bits for conversion n+1 can be overlapped with conversion ‘n’ to allow for a conversion every 16 clock cycles, as shown in Figure 6. This figure also shows pos-sible serial communication occurring with other serial pe-programmable gate arrays (FPGAs) or application specific integrated circuits (ASICs). Note that this effectively in-creases the maximum conversion rate of the converter be-yond the values given in the specification tables, which assume 16 clock cycles per conversion.FIGURE 8. Maximum Conversion Rate, 15-Clocks per Conversion.®11ADS7843Data FormatThe ADS7843 output data is in Straight Binary format asshown in Figure 9. This figure shows the ideal output codefor the given input voltage and does not include the effectsof offset, gain, or noise.FIGURE 9. Ideal Input Voltages and Output Codes.8-Bit ConversionThe ADS7843 provides an 8-bit conversion mode that canbe used when faster throughput is needed and the digitalresult is not as critical. By switching to the 8-bit mode, aconversion is complete four clock cycles earlier. This couldbe used in conjunction with serial interfaces that provide 12-bit transfers or two conversions could be accomplished withthree 8-bit transfers. Not only does this shorten each conver-sion by four bits (25% faster throughput), but each conver-sion can actually occur at a faster clock rate. This is becausethe internal settling time of the ADS7843 is not as critical—settling to better than 8 bits is all that is needed. The clockrate can be as much as 50% faster. The faster clock rate andfewer clock cycles combine to provide a 2x increase inconversion rate.POWER DISSIPATIONThere are two major power modes for the ADS7843: full power(PD1 - PD0 = 11B ) and auto power-down (PD1 - PD0 = 00B ).When operating at full speed and 16-clocks per conversion (asshown in Figure 6), the ADS7843 spends most of its timeacquiring or converting. There is little time for auto power-down, assuming that this mode is active. Therefore, the differ-ence between full power mode and auto power-down is negli-gible. If the conversion rate is decreased by simply slowing thefrequency of the DCLK input, the two modes remain approxi-mately equal. However, if the DCLK frequency is kept at themaximum rate during a conversion but conversions are simplydone less often, the difference between the two modes isdramatic.Figure 10 shows the difference between reducing the DCLK frequency (“scaling” DCLK to match the conversion rate) or maintaining DCLK at the highest frequency and reducing the number of conversions per second. In the later case, the converter spends an increasing percentage of its time inpower-down mode (assuming the auto power-down mode isactive).Another important consideration for power dissipation is the reference mode of the converter. In the single-ended refer-ence mode, the converter’s internal switches are on only when the analog input voltage is being acquired (see Figure 5). Thus, the external device, such as a resistive touch screen, is only powered during the acquisition period. In the differential reference mode, the external device must be powered throughout the acquisition and conversion periods (see Figure 5). If the conversion rate is high, this could substantially increase power YOUT The following layout suggestions should provide the most optimum performance from the ADS7843. However, many portable applications have conflicting requirements con-cerning power, cost, size, and weight. In general, most portable devices have fairly “clean” power and grounds because most of the internal components are very low power. This situation would mean less bypassing for the converter’s power and less concern regarding grounding.Still, each situation is unique and the following suggestions should be reviewed carefully.For optimum performance, care should be taken with the physical layout of the ADS7843 circuitry. The basic SAR architecture is sensitive to glitches or sudden changes on the power supply, reference, ground connections, and digital inputs that occur just prior to latching the output of the analog comparator. Thus, during any single conversion foran ‘n-bit’ SAR converter, there are n ‘windows’ in whichFIGURE 10.Supply Current vs Directly Scaling the Fre-quency of DCLK with Sample Rate or Keeping DCLK at the Maximum Possible Frequency.®12ADS7843large external transient voltages can easily affect the conver-sion result. Such glitches might originate from switchingpower supplies, nearby digital logic, and high power de-vices. The degree of error in the digital output depends onthe reference voltage, layout, and the exact timing of theexternal event. The error can change if the external eventchanges in time with respect to the DCLK input.With this in mind, power to the ADS7843 should be cleanand well bypassed. A 0.1µF ceramic bypass capacitor shouldbe placed as close to the device as possible. A 1µF to 10µFcapacitor may also be needed if the impedance of theconnection between +V CC and the power supply is high.The reference should be similarly bypassed with a 0.1µFcapacitor. If the reference voltage originates from an opamp, make sure that it can drive the bypass capacitor withoutoscillation. The ADS7843 draws very little current from thereference on average, but it does place larger demands on thereference circuitry over short periods of time (on each risingedge of DCLK during a conversion).The ADS7843 architecture offers no inherent rejection of noise or voltage variation in regards to the reference input.This is of particular concern when the reference input is tied to the power supply. Any noise and ripple from the supply will appear directly in the digital results. While high fre-quency noise can be filtered out, voltage variation due to line frequency (50Hz or 60Hz) can be difficult to remove.The GND pin should be connected to a clean ground point.In many cases, this will be the “analog” ground. Avoid connections which are too near the grounding point of a microcontroller or digital signal processor. If needed, run a ground trace directly from the converter to the power supply entry or battery connection point. The ideal layout will include an analog ground plane dedicated to the converter and associated analog circuitry.In the specific case of use with a resistive touch screen, care should be taken with the connection between the converter and the touch screen. Since resistive touch screens have fairly low resistance, the interconnection should be as shortand robust as possible. Longer connections will be a sourceof error, much like the on-resistance of the internal switches.Likewise, loose connections can be a source of error whenthe contact resistance changes with flexing or vibrations.。
