| FEATURES DESCRIPTION2• HIGH-SPEED, 16-BIT PARALLELThe DAC712 is a complete 16-bit resolutionDOUBLE-BUFFERED INTERFACEdigital-to-analog (D/A) converter with 16 bits ofmonotonicity over temperature.• VOLTAGE OUTPUT: ±10V• 13-, 14-, AND 15-BIT LINEARITY GRADESThe DAC712 has a precision +10Vtemperature-compensated voltage reference, ±10V• 16-BIT MONOTONIC OVER TEMPERATUREoutput amplifier, and 16-bit port bus interface.(L GRADE)The digital interface is fast, 60ns minimum write pulse• POWER DISSIPATION: 600mW maxwidth, double-buffered, and has a CLEAR function• GAIN AND OFFSET ADJUST:that resets the analog output to bipolar zero.Convenient for Auto-Cal D/A ConvertersGAIN and OFFSET adjustment inputs are arranged• 28-LEAD DIP AND SOIC PACKAGESso that they can be easily trimmed by external D/Aconverters as well as by potentiometers.The DAC712 is available in two linearity errorperformance grades: ±4LSB and ±2LSB, and threedifferential linearity grades: ±4LSB, ±2LSB, and±1LSB. The DAC712 is specified at power-supplyvoltages of ±12V and ±15V.The DAC712 is packaged in a 28-pin, 0.3" wideplastic DIP and in a 28-lead, wide-body plastic SOIC.The DAC712P, U, PB, and UB are specified over the–40°C to +85°C temperature range and theDAC712PK, UK, PL, and UL are specified over the0°C to +70°C range.DB0 DB15Input LatchA1A016WRCLRD/A Latch16Reference16-Bit D/A ConverterCircuitVOUTVGain Adjust REF OUT Bipolar Offset Adjust+10V1Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of TexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.2All trademarks are the property of their respective owners..Copyright 2000–2009, Texas Instruments IncorporatedProducts conform to specifications per the terms of the TexasInstruments standard warranty.

Texas Instruments recommends that all integrated circuits be handled withappropriate precautions. Failure to observe proper handling and installation procedures can cause damage.ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be moresusceptible to damage because very small parametric changes could cause the device not to meet its published specifications.(1)PACKAGE/ORDERING INFORMATIONDIFFERENTIALLINEARITY ERROR MAX LINEARITY ERROR MAX PACKAGE- PACKAGE SPECIFIEDPRODUCT AT +25°C AT +25°C LEAD DESIGNATOR TEMPERATURE RANGEDAC712P ±4LSB ±4LSB PDIP-28 NT –40°C to +85°CDAC712U ±4LSB ±4LSB SOIC-28 DW –40°C to +85°CDAC712PB ±2LSB ±2LSB PDIP-28 NT –40°C to +85°CDAC712UB ±2LSB ±2LSB SOIC-28 DW –40°C to +85°CDAC712PK ±2LSB ±2LSB PDIP-28 NT 0°C to +70°CDAC712UK ±2LSB ±2LSB SOIC-28 DW 0°C to +70°CDAC712PL ±2LSB ±1LSB PDIP-28 NT 0°C to +70°CDAC712UL ±2LSB ±1LSB SOIC-28 DW 0°C to +70°C(1) For the most current package and ordering information see the Package Option Addendum at the end of this document, or see the TIweb site at .
