Description

General part information

LTC7545A Series

The LTC7545A 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 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.ApplicationsProcess Control and Industrial AutomationSoftware Controlled Gain AdjustmentDigitally Controlled Filter and Power SuppliesAutomatic Test Equipment
