The LTC
digital-to-analog converter (DAC). It includes two current
output multiplying CMOS DACs and an easy SPI compat-
ible serial interface with daisy-chain output. An asynchro-
nous CLR pin sets both DACs to zero scale.
Excellent accuracy, stability and versatility are combined
with the smallest package available for a dual 12-bit
multiplying DAC.
Parts are available in 16-pin PDIP and narrow SO pack-
ages and are specified over the commercial and industrial
temperature ranges.
