Product Summary
The LTC7545ACSW is a 12-bit multiplying digital-to-analog converter (DAC) with a microprocessor compatible parallel input. It is a superior pin compatible replacement for the industry standard AD7545A and AD7545. Improvements include better accuracy, better stability over temperature and supply variations and lower sensitivity to output amplifier offset. This very versatile DAC LTC7545ACSW is useful for 2-quadrant and 4-quadrant multiplying, programmable gain and filtering and single supply noninverting voltage output operation. Parts are available in 20-pin PDIP and SO packages and commercial and industrial temperature grades.
