Product Details

The LTC1590 is a dual, serial input 12-bit multiplying digital-to-analog converter (DAC). It includes two current output multiplying CMOS DACs and an easy SPI compatible serial interface with daisy-chain output. An asynchronous 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 packages and are specified over the commercial and industrial temperature ranges.
