Product Introduction

Overview

The TLC7225CDWR, produced by Texas Instruments, is a highly integrated digital-to-analog converter (DAC) that features four 8-bit voltage-output DACs. This device is designed to provide a compact and reliable solution for various applications requiring multiple DACs. The TLC7225CDWR includes output buffer amplifiers and interface logic with double register-buffering, making it suitable for use in microprocessor-based systems. It is fabricated using the LinBiCMOS™ process, which allows for the integration of high-speed digital logic and precision analog circuits on the same chip.
