j:0.003% Maximum Nonlinearity Low Gain Driftj:7ppm/oC 0 to + 70°C Operation (AD DAC71, AD DAC71H, AD DAC72C) -25°C to + 85°C Operation (AD DAC72) Current and Voltage Models Available Improved Second-Source Low Cost PRODUCT DESCRIPTION The AD DAC71 and AD DACn are high resolution16-bit hybrid IC digital-to-analogconvertersincludingreference,scaling resistorsand output amplifier(V models). The devicesofferoutstandingaccuracy,includingmaximum linearityerrorof 0.003% at room temperatureand maximum gaindriftsof 15ppmrC (AD DAC71, AD DAC7IH, AD DACnC) and 7ppm/°C (AD DACn). This performance ispossibledue to the innovativedesign,usingproprietarymonolithicD/A converter chips.Laser-trimmed thin fllmresistorsprovide the linearity and wide temperature range forguaranteedmonotonicity. The AD DAC71 and AD DACn digitalinputsare ITL-com- patible.Coding iscomplementary straightbinary(CSB) for unipolaroutput versionsand complementary offsetbinary(COB) forbipolaroutput versions. Allversionsarepackaged ina 24-pinmetal DIP. The AD DAC71, AD DAC71H and AD DACnC are specifiedforoperationfrom 0 to + 70°C, and the AD DACn isspecifiedfrom - 25°C to + 85°C. The AD DAC7IH, AD DACn and AD DACnC are suppliedin hermetically-sealedpackages. The AD DAC71 and AD DACn areintendedtoserveasimproved second sourcesto DAC71 and DACn devicesfrom other manufacturers. *Covered by Patent Numbers: 3,978,473; RE28,633; 4,020,486; 3,747,088; HighResolution 16-Bit0/A Converters AD oAC71/AoDAC72* AD DAC71/AD DAC 72 FUNCTIONAL BLOCK DIAGRAM if1 SUMMING JUNCTION BIT 9 AD DAC71/AD DAC72 PRODUCT HIGHLIGHTS 1. The AD DAC7l and AD DACn provide l6-bitresolution with 0.003% linearityerror. 2. The proprietarychipsused in the hybrid designprovide excellentstabilityover temperatureand improved reliability. 3. Unipolarand bipolarcurrentand voltageoutput versionsare availableto filla wide range of system requirements. 4. The AD DAC71 and AD DACn areimproved second source replacementsforDAC71 and DACn devicesfrom other manufacturers. OBSOLETE
