Product Introduction

Overview

The ADS8344EB, manufactured by Texas Instruments, is an 8-channel, 16-bit, sampling Analog-to-Digital (A/D) converter. It features a synchronous serial interface and is designed for low power consumption and high speed operation. This makes it ideal for battery-operated systems, including personal digital assistants, portable multi-channel data loggers, and various measurement equipment. The device operates on a single supply voltage ranging from 2.7V to 5V and includes an on-board multiplexer. It also has a shutdown mode that significantly reduces power dissipation to under 15µW, making it highly efficient for power-sensitive applications.
