DAC7545KUG4

Digital To Analog Converters Overview

The DAC7545KUG4 is a CMOS, 12-bit multiplying digital-to-analog converter manufactured by Texas Instruments. It features input data latches and operates on a single +5V to +15V supply. The device utilizes laser-trimmed thin-film resistors for true linearity and supports TTL/CMOS logic interfaces. Key electrical parameters include a typical gain temperature coefficient of 2ppm/°C, maximum output leakage current of 10nA, and maximum output capacitance of 70pF. Current settling time is specified at 2µs to within 1/2 LSB. It is housed in an SO-20 package and functions over the commercial temperature range of -40°C to +85°C.
