Overview
The TLC7528EDWR, produced by Texas Instruments, is a dual 8-bit multiplying digital-to-analog converter (DAC) designed for high-performance applications. This device features separate on-chip data latches for each DAC, ensuring exceptionally close DAC-to-DAC matching. It is easily interfaced to microprocessors and is suitable for various microprocessor-controlled gain-setting and signal-control applications. The TLC7528EDWR operates in voltage mode, producing a voltage output rather than a current output, and is compatible with a wide range of power supply voltages from 5V to 15V.
