Product Introduction

Overview

The AD7228KR, produced by Analog Devices Inc., is a highly integrated digital-to-analog converter (DAC) chip. It contains eight 8-bit voltage mode DACs, each with output buffer amplifiers and interface logic, all on a single monolithic chip. This device is fabricated using an all ion implanted, high speed, linear-compatible CMOS (LC2MOS) process, which allows for the integration of high speed digital logic and precision analog circuits. The AD7228KR is designed to operate with either single or dual supplies, with specified performance guaranteed for input reference voltages from 2 V to 10 V. It features a common 8-bit data bus with individual DAC latches, making it versatile for interfacing with microprocessors.
