The ADS1222IPWR is a precision 24-bit delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It integrates a 2-channel input multiplexer, allowing both differential and single-ended inputs. The device achieves an effective resolution of 20 bits and a data rate of 240 SPS with a 4 MHz clock. Key features include an on-chip temperature sensor, self-calibration, and a simple 2-wire SPI interface. The ADC operates from a 2.7V to 5.5V analog supply and consumes only 300 µA typical current. It is housed in a 14-pin TSSOP package and is rated for -40°C to 85°C operation. Typical applications include hand-held instrumentation, portable medical equipment, industrial process control, and weigh scales.
