Product Summary

The ADS1212P is a precision, wide dynamic range, delta-sigma Analog-to-Digital (A/D) converter with 24-bit resolution operating from a single +5V supply. The differential inputs are ideal for direct connection to transducers or low-level voltage signals.The ADS1212P is designed for high-resolution measurement applications in smart transmitters, industrial process control, weigh scales, chromatography and portable instrumentation. The ADS1212P includes a flexible synchronous serial interface that is SPI compatible and also offers a two-wire control mode for low-cost isolation.
