Product Introduction

Overview

The TLC7528CNS, produced by Texas Instruments, is a dual 8-bit 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 compatible with various microprocessor buses and output ports. The TLC7528CNS operates in voltage mode, producing a voltage output, and is suitable for microprocessor-controlled gain-setting and signal-control applications.
