AD DAC71/AD DAC72
PRODUCT DESCRIPTION
The AD DAC71 and AD DACn are high resolution 16-bit
hybrid IC digital-to-analog converters including reference, scaling
resistors and output amplifier (V models).
PRODUCT HIGHLIGHTS
1. The AD DAC7l and AD DACn provide l6-bit resolution
with 0.003% linearity error.
2. The proprietary chips used in the hybrid design provide
The devices offer outstanding accuracy, including maximum
excellent stability over temperature and improved reliability.
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.
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-com-
patible. 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.
