Product Introduction

Overview

The AD974AN, produced by Analog Devices Inc., is a comprehensive data acquisition system integrated into a single chip. This component combines a four-channel input multiplexer, a high-speed 16-bit successive-approximation switched-capacitor analog-to-digital converter (ADC), and an internal 2.5 V reference. It operates from a single +5 V power supply and features a power-down mode to minimize power consumption. The AD974AN is designed for efficient data transfer with a low number of interconnect signals, making it suitable for various data acquisition applications.
