Product Introduction

Overview

The ADS7828E/250 is a single-supply, low-power, 12-bit data acquisition device produced by Texas Instruments. It features a serial I2C interface and an 8-channel multiplexer, making it ideal for applications requiring the A/D converter to be close to the input source in remote locations and for applications requiring isolation. The device includes a sample-and-hold amplifier and an internal, asynchronous clock. It is available in a TSSOP-16 package and operates within a voltage range of 2.7V to 5V, with an internal 2.5V reference voltage.
