Overview
The TLC7528IN, produced by Texas Instruments, is a dual 8-bit multiplying digital-to-analog converter (DAC). This device is designed with separate on-chip data latches and features exceptionally close DAC-to-DAC matching. It operates from a 5V to 15V power supply and is characterized for operation from −25°C to +85°C, making it suitable for a wide range of microprocessor-controlled applications.
The TLC7528IN is easily interfaced to microprocessors and digital signal processors (DSPs), including the TMS320 series. It uses CMOS technology and supports voltage-mode operation, producing a voltage output rather than a current output.
