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. The ADC is designed to easily connect to microcontrollers, such as the MSP
