Product Introduction

Overview

The AD974BNZ, produced by Analog Devices Inc., is a comprehensive data acquisition system integrated into a single chip. It combines a four-channel input multiplexer, a high-speed 16-bit successive-approximation switched-capacitor ADC, and an internal +2.5 V reference. This device operates from a single +5 V power supply and features a power-down mode to minimize power consumption. The AD974 is designed for efficient data transfer with a low number of interconnect signals, making it suitable for various applications requiring precise analog-to-digital conversion.
