ADS1210 概述
The ADS1210 and ADS1211 are precision, wide dynamic range, delta-sigma analog-to-digital converters with 24-bit resolution operating from a single +5V supply.
The ADS1210 and ADS1211 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 ADS1210 is a single channel converter and is offered in both 18-pin DIP and 18-lead SOIC packages. The ADS1211 includes a 4-channel input multiplexer and is available in 24-pin DIP, 24-lead SOIC, and 28-lead SSOP packages
