The devices offer outstanding accuracy, including maximum linearity error of 0.003% at room temperature and maximum gain drifts of 15ppmrC (AD DAC71, AD DAC7IH, AD DACnC) and 7ppm/°C (AD DACn). This performance is possible due to the innovative design, using proprietary monolithic D/A converter chips. Laser-trimmed thin fllm resistors provide the linearity and wide temperature range for guaranteed monotonicity. TE DAC72 PRODUCT HIGHLIGHTS 1. The AD DAC7l and AD DACn with 0.003% linearity error. provide l6-bit resolution 2. The proprietary chips used in the hybrid design provide excellent stability over temperature and improved reliability. 3. Unipolar and bipolar current and voltage output versions are available to fill a wide range of system requirements. 4. The AD DAC71 and AD DACn are improved second source replacements for DAC71 and DACn devices from other manufacturers. The AD DAC71 and AD DACn digital inputs are ITL-compatible. Coding is complementary straight binary (CSB) for unipolar output versions and complementary offset binary (COB) for bipolar output versions. All versions are packaged in a 24-pin metal DIP. The AD DAC71, AD DAC71H and AD DACnC are specified for operation from 0 to + 70°C, and the AD DACn is specified from - 25°C to + 85°C. The AD DAC7IH, AD DACn and AD DACnC are supplied in hermetically-sealed packages. The AD DAC71 and AD DACn are intended to serve as improved second sources to DAC71 and DACn devices from other manufacturers. *Covered by Patent Numbers: 3,978,473; RE28,633; 3,803,590; 3,961,326; 4,213,806; 4,136,349. 4,020,486; 3,747,088; ~ ~-~~ SPECIFICATIONS (@ TA = AD DAC71/AD DAC71H MIN TYP MAX MODEL DIGITAL INPUTS Resolution Logic Levels (TTL-Compatible)t Logical "I" Logical "0" + 25°C,ratedpowersuppliesunlessotherwise noted) MIN AD DAC72C TYP MAX 16 MIN AD DAC72 TYP MAX 16 + 2.4 +0 +5.5 +0.4 UNITS 16 +2.4 +0 + 5.5 +0.4 Birs +2.4 +0 +5.5 +0.4 Vdc Vdc =0.003 =0.15 =0.25 =2.0 = 10.0 = 1.0 =5.0 +70 % ofFSR3 % % mV mV '" 19 ",II ppmofFSRI'C ppmofFSRI'C ACCURACY' Linearity Error at 2S'C Gain Error', Voltage Current Offset Error" Voltage, Unipolar Voltage, Bipolar Current, Unipolar Current, Bipolar MonotonicilY Temp.
