Product Summary

The ADS1112IDRCT is a precision, continuously self-calibrating Analog-to-Digital (A/D) converter with two differential or three single-ended channels and up to 16 bits of resolution in the small MSOP-10 and leadless QFN-style (small-outline, no-lead) packages. The onboard 2.048V reference provides an input range of ±2.048V differentially. The ADS1112IDRCT uses an I2C-compatible serial interface and has two address pins that allow a user to select one of the eight I2C Slave addresses. The ADS1112IDRCT operates from a single power supply ranging from 2.7V to 5.5V. The applications of the ADS1112IDRCT include portable instrumentation, industrial process control, smart transmitters, consumer goods, factory automation, temperature measurement.
