Product Introduction

Overview

The AD7868ANZ, produced by Analog Devices Inc., is a complete 12-bit analog input/output (I/O) system. This integrated circuit includes 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 buffer amplifier. The device also features on-chip voltage references for both the ADC and DAC, ensuring high precision and stability. It operates from ±5 V power supplies and has a small footprint, available in 24-pin plastic or hermetic dual-in-line package (DIP) and 28-pin plastic small outline IC (SOIC) packages.
