ADS1212 概述

The ADS1212 and ADS1213 are precision, wide dynamic range, delta-sigma Analog-to-Digital (A/D) converters with 24-bit resolution operating from a single +5V supply.

The ADS1212 and ADS1213 are designed for high-resolution measurement applications in smart transmitters, industrial process control, weigh scales, chromatography and portable instrumentation. Both converters include a flexible synchronous serial interface which is SPI compatible and also offers a two-wire control mode for low-cost isolation.

The ADS1212 is a single channel converter and is offered in both DIP-18 and SO-18 packages. The ADS1213 includes a 4-channel input multiplexer and is available in DIP-24, SO-24, and SSOP-28 packages.
