AD974 - 4-Channel/ 16-Bit/ 200 kSPS Data Acquisition System

Datasheet Summary

Description

The AD974 is a four-channel, data acquisition system with a serial interface.

The part contains an input multiplexer, a highspeed 16-bit sampling ADC and a +2.5 V reference.

All of this operates from a single +5 V power supply that also has a powerdown mode.

Features

  • Fast 16-Bit ADC with 200 kSPS Throughput Four Single-Ended Analog Input Channels Single +5 V Supply Operation Input Ranges: 0 V to +4 V, 0 V to +5 V and ؎ 10 V 120 mW Max Power Dissipation Power-Down Mode 50 ␮W Choice of External or Internal 2.5 V Reference On-Chip Clock Power-Down Mode V1A V1B 4-Channel, 16-Bit, 200 kSPS Data Acquisition System AD974.
