Product Description

The ADS1222IPWT is a 2-channel 24-bit delta-sigma Analog-to-digital Converter (ADC) offers excellent performance and low power. The ADC is well-suited for demanding, high-resolution measurements, especially in portable systems and other space-saving and power-constrained applications. A delta-sigma (ΔΣ) modulator and digital filter form the basis of the A/D converter. The analog modulator has a ±5V differential input range. An input multiplexer (mux) is used to select between two separate differential input channels. A buffer can be selected to increase the input impedance of the measurement. A simple 2-wire serial interface provides all the necessary control. Data retrieval, self-calibration and Standby mode are handled with a few simple waveforms. When only single conversions are needed, the ADC can be quickly shut down while idle between measurements to dramatically reduce the overall power consumption.
