Overview
The TLC7528EDWG4, produced by Texas Instruments, is a dual 8-bit digital-to-analog converter (DAC) designed with separate on-chip data latches. This component is part of the TLC7528 series, which includes the TLC7528C, TLC7528E, and TLC7528I models. The TLC7528EDWG4 is characterized for operation from -40°C to +85°C, making it suitable for a wide range of applications. It operates from a 5V to 15V power supply and dissipates less than 15 mW (typical). The device features exceptionally close DAC-to-DAC matching and is easily interfaced to microprocessors and digital signal processors (DSPs), including the TMS320 series.
