Analog inputs can withstand constant 70VP-P levels with ±15V supplies. Digital inputs will also sustain continuous faults up to 4V greater than either supply. In addition, signal sources are protected from short circuiting should multiplexer supply loss occur. Each input presents 1kΩ of resistance under this condition. These features make the HI-546, HI-547, HI-548 and HI-549 ideal for use in systems where the analog inputs originate from external equipment or separately powered circuitry. All devices are fabricated with 44V Dielectrically Isolated CMOS technology. The HI-546 is a single 16-Channel, the HI-547 is an 8-Channel differential, the HI-548 is a single 8-Channel and the HI-549 is a 4-Channel differential device. If input overvoltage protection is not needed the HI-506/507/508/509 multiplexers are recommended. For further information see Application Notes AN520 and AN521.

These devices are designed for serial interface with a microprocessor or peripheral through a 3-state data output and an analog input. The TLC548 and TLC549 use only the input/output clock (I/O CLOCK) input along with the chip select (CS) input for data control. The maximum I/O CLOCK input frequency of the TLC548 is 2.048 MHz, and the I/O CLOCK input frequency of the TLC549 is specified up to 1.1 MHz.AVAILABLE OPTIONSPACKAGET A SMALL OUTLINE(D)PLASTIC DIP(P)0°C to 70°C TLC548CD TLC549CD TLC548CP TLC549CP –40°C to 85°CTLC548ID TLC549IDTLC548IP TLC549IPCopyright © 1996, Texas Instruments IncorporatedPRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instruments standard warranty.

The on-chip system clock allows internal device operation to proceed independently of serial input/output data timing and permits manipulation of the TLC548 and TLC549 as desired for a wide range of software and hardware requirements. The I/O CLOCK together with the internal system clock allow high-speed data transfer and conversion rates of 45500 conversions per second for the TLC548, and 40000 conversions per second for the TLC549.Additional TLC548 and TLC549 features include versatile control logic, an on-chip sample-and-hold circuit that can operate automatically or under microprocessor control, and a high-speed converter with differential high-impedance reference voltage inputs that ease ratiometric conversion, scaling, and circuit isolation from logic and supply noises. Design of the totally switched-capacitor successive-approximation converter circuit allows conversion with a maximum total error of ±0.5 least significant bit (LSB) in less than 17 µs.The TLC548C and TLC549C are characterized for operation from 0°C to 70°C.

For proper operation, the positive reference voltage V ref+, must be at least 1 V greater than the negative reference voltage, V ref–. In addition, unadjusted errors may increase as the differential reference voltage, V ref+ – V ref–,falls below 4.75 V.4.This is the time required for the I/O CLOCK input signal to fall from V IH min to V IL max or to rise from V IL max to V IH min. In the vicinityof normal room temperature, the devices function with input clock transition time as slow as 2 µs for remote data acquisition applications in which the sensor and the ADC are placed several feet away from the controlling microprocessor.5.To minimize errors caused by noise at the CS input, the internal circuitry waits for two rising edges and one falling edge of internalsystem clock after CS ↓ before responding to control input signals.

Each contains an internal system clock, sample-and-hold function, 8-bit A/D converter, data register, and control logic circuitry. For flexibility and access speed, there are two control inputs: I/O CLOCK and chip select (CS). These control inputs and a TTL-compatible 3-state output facilitate serial communications with a microprocessor or minicomputer. A conversion can be completed in 17 µs or less, while complete input-conversion-output cycles can be repeated in 22 µs for the TLC548 and in 25 µs for the TLC549.The internal system clock and I/O CLOCK are used independently and do not require any special speed or phase relationships between them. This independence simplifies the hardware and software control tasks for the device.Due to this independence and the internal generation of the system clock, the control hardware and software need only be concerned with reading the previous conversion result and starting the conversion by using the I/O clock. In this manner, the internal system clock drives the “conversion crunching” circuitry so that the control hardware and software need not be concerned with this task.When CS is high, DATA OUT is in a high-impedance condition and I/O CLOCK is disabled. This CS control function allows I/O CLOCK to share the same control logic point with its counterpart terminal when additional TLC548 and TLC549 devices are used. This also serves to minimize the required control logic terminals when using multiple TLC548 and TLC549 devices.The control sequence has been designed to minimize the time and effort required to initiate conversion and obtain the conversion result. A normal control sequence is:1.CS is brought low. To minimize errors caused by noise at CS, the internal circuitry waits for two rising edgesand then a falling edge of the internal system clock after a CS ↓ before the transition is recognized. However,upon a CS rising edge, DATA OUT goes to a high-impedance state within the specified t dis even though the rest of the integrated circuitry does not recognize the transition until the specified t su(CS) has elapsed. This technique protects the device against noise when used in a noisy environment. The most significant bit (MSB)of the previous conversion result initially appears on DATA OUT when CS goes low.2.The falling edges of the first four I/O CLOCK cycles shift out the second, third, fourth, and fifth most significantbits of the previous conversion result. The on-chip sample-and-hold function begins sampling the analog input after the fourth high-to-low transition of I/O CLOCK. The sampling operation basically involves the charging of internal capacitors to the level of the analog input voltage.3.Three more I/O CLOCK cycles are then applied to the I/O CLOCK terminal and the sixth, seventh, and eighthconversion bits are shifted out on the falling edges of these clock cycles.4.The final (the eighth) clock cycle is applied to I/O CLOCK. The on-chip sample-and-hold function begins thehold operation upon the high-to-low transition of this clock cycle. The hold function continues for the next four internal system clock cycles, after which the holding function terminates and the conversion is performed during the next 32 system clock cycles, giving a total of 36 cycles. After the eighth I/O CLOCK cycle, CS must go high or the I/O clock must remain low for at least 36 internal system clock cycles to allow for the completion of the hold and conversion functions. CS can be kept low during periods of multiple conversion. When keeping CS low during periods of multiple conversion, special care must be exercised to prevent noise glitches on the I/O CLOCK line. If glitches occur on I/O CLOCK, the I/O sequence between the microprocessor/controller and the device loses synchronization. When CS is taken high, it must remain high until the end of conversion. Otherwise, a valid high-to-low transition of CS causes a reset condition, which aborts the conversion in progress.A new conversion may be started and the ongoing conversion simultaneously aborted by performing steps 1 through 4 before the 36 internal system clock cycles occur. Such action yields the conversion result of the previous conversion and not the ongoing conversion.TLC548C, TLC548I, TLC549C, TLC549I 8-BIT ANALOG-TO-DIGITAL CONVERTERSWITH SERIAL CONTROLSLAS067C – NOVEMBER 1983 – REVISED SEPTEMBER 19969POST OFFICE BOX 655303 •DALLAS, TEXAS 75265PRINCIPLES OF OPERATIONFor certain applications, such as strobing applications, it is necessary to start conversion at a specific point in time.This device accommodates these applications. Although the on-chip sample-and-hold function begins sampling upon the high-to-low transition of the fourth I/O CLOCK cycle, the hold function does not begin until the high-to-low transition of the eighth I/O CLOCK cycle, which should occur at the moment when the analog signal must be converted. The TLC548 and TLC549 continue sampling the analog input until the high-to-low transition of the eighth I/O CLOCK pulse. The control circuitry or software then immediately lowers I/O CLOCK and starts the holding function to hold the analog signal at the desired point in time and starts the conversion.PACKAGING INFORMATIONOrderableDeviceStatus (1)Package Type Package DrawingPins Package Qty Eco Plan (2)Lead/Ball Finish MSL Peak Temp (3)TLC548CD ACTIVE SOIC D 875Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC548CDG4ACTIVE SOIC D 875Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC548CDR ACTIVE SOIC D 82500Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC548CDRG4ACTIVE SOIC D 82500Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC548CP ACTIVE PDIP P 850Pb-Free (RoHS)CU NIPDAU N /A for Pkg Type TLC548CPE4ACTIVE PDIP P 850Pb-Free (RoHS)CU NIPDAU N /A for Pkg Type TLC548ID ACTIVE SOIC D 875Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC548IDG4ACTIVE SOIC D 875Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC548IDR ACTIVE SOIC D 82500Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC548IDRG4ACTIVE SOIC D 82500Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC548IP ACTIVE PDIP P 850Pb-Free (RoHS)CU NIPDAU N /A for Pkg Type TLC548IPE4ACTIVE PDIP P 850Pb-Free (RoHS)CU NIPDAU N /A for Pkg Type TLC549CD ACTIVE SOIC D 875Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC549CDG4ACTIVE SOIC D 875Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC549CDR ACTIVE SOIC D 82500Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC549CDRG4ACTIVE SOIC D 82500Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC549CP ACTIVE PDIP P 850Pb-Free (RoHS)CU NIPDAU N /A for Pkg Type TLC549CPE4ACTIVE PDIP P 850Pb-Free (RoHS)CU NIPDAU N /A for Pkg Type TLC549ID ACTIVE SOIC D 875Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC549IDG4ACTIVE SOIC D 875Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC549IDR ACTIVE SOIC D 82500Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC549IDRG4ACTIVE SOIC D 82500Green (RoHS &no Sb/Br)CU NIPDAU Level-1-260C-UNLIM TLC549IP ACTIVE PDIP P 850Pb-Free (RoHS)CU NIPDAU N /A for Pkg Type TLC549IPE4ACTIVE PDIP P 850Pb-Free (RoHS)CU NIPDAU N /A for Pkg Type TLC549IPSACTIVESOPS880Green (RoHS &no Sb/Br)CU NIPDAULevel-1-260C-UNLIMPACKAGE OPTION ADDENDUM6-Nov-2006Addendum-Page 1分销商库存信息:TITLC549IP TLC549CP TLC549CD TLC548CP TLC549ID TLC548IP TLC548ID TLC548CD TLC549CDR TLC549CDRG4TLC549IDR TLC549IDRG4 TLC548CDR TLC548CDRG4TLC549IPSR TLC549IPSRG4TLC548IDR TLC548IDRG4 TLC549CPE4TLC549IPE4TLC549CDG4 TLC548CPE4TLC549IDG4TLC548IPE4 TLC549IPS TLC549IPSG4TLC548CDG4 TLC548IDG4。

FOXBORO ®The FBM214 HART ® Communication Input Interface Module provides eight input channels, each accepting a 4 to 20mA analog signal or a digital HART signal superimposed on a 4 to 20 mA analog input signal.FEATURESKey features of the FBM214 module are:Eight analog input channels, each accepting oneof the following inputs:•Standard 4 to 20 mA analog sensor signal •Digital HART Frequency Shift Keying (FSK) signal superimposed on a 4 to 20 mA analog input signal.FSK modem dedicated to each input channel forbi-directional digital communications with a HART field deviceAnalog to digital conversion of each of the 4to20mA input signals from the HART devicesSupport for the HART universal commandsnecessary to interface the field device with the I/A Series ® system databaseGalvanic isolation of the group of 8 inputchannels from ground and module logicCompact, rugged design suitable for enclosure inClass G3 (harsh) environmentsHigh accuracy achieved by sigma-delta dataconversions for each channelTermination Assemblies (TAs) for locally orremotely connecting field wiring to the FBM214Termination Assemblies for per channel internallyand/or externally loop powered transmitters.PSS 21H-2Z14 B4 Page 2OVERVIEWThe FBM214 HART Communication Input Interface Module contains eight 4to20mA group isolated analog input channels. The FBM214 supports any mix of standard 4to20mA devices and HART devices.The FBM214 serves as a HART communications field device host, enabling the I/A Series system to request and receive two digital messages per second from the field device. The message pass-through capability can be used to support HART universal, common practice, and device-specific commands, but not the burst communication mode. These commands are implemented using the Intelligent Field Device Configurator (IFDC — refer toPSS 21S-8A3 B3 for details).The FBM214 provides a common isolated power supply to power all eight channels. Optionally, the channels can be powered by an external power supply. However, when a common external power supply is used with two or more channels, a Cable Balun module is required to prevent channel cross talk.COMPACT DESIGNThe FBM214 has a compact design, with a rugged extruded aluminum exterior for physical protection of the circuits. Enclosures specially designed for mounting the FBMs provide various levels of environmental protection, up to harsh environments per ISA Standard S71.04.HIGH ACCURACYFor high accuracy, the module incorporates a Sigma-Delta converter which can provide new analog input values for each channel every 100 milliseconds.VISUAL INDICATORSLight-emitting diodes (LEDs) incorporated into the front of the module provide visual indication of the module’s operational status, and communication activity on the channels.EASY REMOVAL/REPLACEMENTThe module can be removed/replaced without removing field device termination cabling, power, or communications cabling.FIELDBUS COMMUNICATIONA Fieldbus Communication Module or a Control Processor interfaces the redundant 2 Mbps module Fieldbus used by the FBMs. The FBM214 module accepts communication from either path (A or B) of the redundant 2 Mbps fieldbus – should one path fail or be switched at the system level, the module continues communication over the active path.The use of an external power supply common to two or more loops requires a Cable Balun Module to maintain communication signal line balance.MODULAR BASEPLATE MOUNTINGThe module mounts on a modular baseplate which accommodates up to four or eight FBMs. The modular baseplate is either DIN rail mounted or rack mounted, and includes signal connectors for redundant fieldbus, redundant independent dc power, and termination cables.TERMINATION ASSEMBLIESField input signals connect to the FBM subsystem via DIN rail mounted TAs. The TAs used with theFBM214 are described in “TERMINATION ASSEMBLIES AND CABLES” on page8.PSS 21H-2Z14 B4Page 3CABLE BALUN MODULEThe Cable Balun module is used to maintain digital communication line balance for HART Transmitter to FBM loops that are powered from a common external power supply. This powering effectively connects one line of each loop together. Without the Baluns, in each loop so powered, the common connection at the external power supply, would cause near end crosstalk at the system end of the loop wiring cable. Loops using FBM internal power source do not require Baluns.The Cable Balun module contains multiple Baluns. One Balun segment is interconnected in each loop powered from an external power supply per the diagram above. There is one Cable Balun module.Figure 1.

Ifthe current limit circuit shorts out, the current islimited to about 85 mA.FBM INPUT IMPEDANCE280 Ω minimumFBM INTERNAL POWER FOR FIELD DEVICE24 V dc ±10% common power supply for allchannels. Loop load limited to one device perchannel.ISOLATIONThe channels are not galvanically isolated fromeach other, but are galvanically isolated (bothoptical and transformer isolation) as a group from ground and module logic. Inputs use an internal FBM isolated power supply for field power. Themodule withstands, without damage, a potential of 600 V ac applied for one minute between the group-isolated channels and earth (ground).CAUTIONThis does not imply that these channels areintended for permanent connection tovoltages of these levels. Exceeding the limitsfor input voltages, as stated elsewhere in thisspecification, violates electrical safety codesand may expose users to electric shock. Fieldbus CommunicationCommunicates with its associated FCM or FCP via the redundant 2 Mbps module FieldbusHEAT DISSIPATION4 W (maximum)(1)The maximum allowable distance decreases when the loop is operated through an intrinsic safety barrier. The maximum distance ofthe field device from the FBM is a function of compliance voltage, wire gauge and voltage drop at the device.(2)In an intrinsic safety application, if a zener barrier is used between the FBM and the field device, the power supply must be set at24V dc +5%, -1%. There are no specific constraints with the use of galvanic barriers.PSS 21H-2Z14 B4Page 5 FUNCTIONAL SPECIFICATIONS (CONTINUED)Power RequirementsINPUT VOLTAGE RANGE (REDUNDANT)24V dc ±5%CONSUMPTION7 W (maximum)Regulatory ComplianceELECTROMAGNETIC COMPATIBILITY (EMC) European EMC Directive 89/336/EECMeets:EN 50081-2 Emission standardEN 50082-2 Immunity standardEN 61326 Annex A (Industrial Levels) CISPR 11, Industrial Scientific and Medical(ISM) Radio-frequency Equipment -Electromagnetic Disturbance Characteristics- Limits and Methods of MeasurementMeets Class A LimitsIEC 61000-4-2 ESD ImmunityContact 4 kV, air 8 kVIEC 61000-4-3 Radiated Field Immunity10 V/m at 80 to 1000 MHzIEC 61000-4-4 Electrical FastTransient/Burst Immunity2 kV on I/O, dc power and communicationlinesIEC 61000-4-5 Surge Immunity2kV on ac and dc power lines; 1kV on I/Oand communications linesIEC 61000-4-6 Immunity to ConductedDisturbances Induced by Radio frequencyFields10 V (rms) at 150 kHz to 80 MHz on I/O,dc power and communication linesIEC 61000-4-8 Power Frequency MagneticField Immunity30 A/m at 50 and 60 HzPRODUCT SAFETY (FBM AND CABLE BALUN) Underwriters Laboratories (UL) for U.S. andCanadaUL/UL-C listed as suitable for use inUL/UL-C listed Class I, Groups A-D;Division 2; temperature code T4 enclosurebased systems.

DESCRIPTION
The OPA549 is a low-cost, high-voltage/high-current operational amplifier ideal for driving a wide variety of loads. This laser-trimmed monolithic integrated circuit provides excellent low-level signal accuracy and high output voltage and current. The OPA549 operates from either single or dual supplies for design flexibility. The input common-mode range extends below the negative supply. The OPA549 is internally protected against over-temperature conditions and current overloads. In addition, the OPA549 provides an accurate, user-selected current limit. Unlike other designs which use a “power” resistor in series with the output current path, the OPA549 senses the load indirectly. This allows the current limit to be adjusted from 0A to 10A with a resistor/potentiometer, or controlled digitally with a voltage-out or current-out Digital-to-Analog Converter (DAC). The Enable/Status (E/S) pin provides two functions. It can be monitored to determine if the device is in thermal shutdown, and it can be forced low to disable the output stage and effectively disconnect the load. The OPA549 is available in an 11-lead power package. Its copper tab allows easy mounting to a heat sink for excellent thermal performance. Operation is specified over the extended industrial temperature range, –40°C to +85°C.

The SAA529x, SAA529xA and SAA549x family of microcontrollers are a derivative of the Philips’ industry-standard 80C51 microcontroller and are intended for use as the central control mechanism in a television receiver. They provide control functions for the television system and include an integrated teletext function. The teletext hardware has the capability of decoding and displaying both 525-line and 625-line World System Teletext. The same display hardware is used both for Teletext and On-Screen Display, which means that the display features give greater flexibility to differentiate the TV set. The family offers both 1 page and 10 page Teletext capability, in a range of ROM sizes. Increasing display capability is offered from the SAA5290 to the SAA5497.
