Product Introduction

Overview

The AD7868BRZ, produced by Analog Devices Inc., is a comprehensive 12-bit analog input/output system. This integrated circuit combines a 12-bit analog-to-digital converter (ADC) with a track-and-hold amplifier and a 12-bit digital-to-analog converter (DAC) with an output amplifier. The device also includes on-chip voltage references for both the ADC and DAC, ensuring high precision and stability. It operates from ±5 V power supplies and features a small 24-pin or 28-pin package, making it suitable for various applications requiring high-speed and precise analog I/O operations.
