Product Summary

The ADS1212U is a 22-bit analog-to-digital converter. The ADS1212U is designed for high-resolution measurement applications in smart transmitters, industrial process control, weigh scales, chromatography and portable instrumentation. The ADS1212U includes a flexible synchronous serial interface that is SPI compatible and also offers a two-wire control mode for low-cost isolation.
