Description for the ADS112C04

The ADS112C04 is a precision, 16-bit,analog-to-digital converter (ADC) that offers many integrated features to reduce system cost andcomponent count in applications measuring small sensor signals. The device features twodifferential or four single-ended inputs through a flexible input multiplexer (MUX), a low-noise,programmable gain amplifier (PGA), two programmable excitation current sources, a voltagereference, an oscillator, and a precision temperature sensor.

The device can perform conversions at data rates up to 2000 samples-per-second (SPS) withsingle-cycle settling. At 20 SPS, the digital filter offers simultaneous 50-Hz and 60-Hz rejectionfor noisy industrial applications. The internal PGA offers gains up to 128. This PGA makes theADS112C04 ideally suited for applications measuring small sensor signals, suchas resistance temperature detectors (RTDs), thermocouples, thermistors, and resistive bridgesensors.

The ADS112C04 features a 2-wire,I2C-compatible interface that supports I2Cbus speeds up to 1 Mbps. Two address pins allow selection of 16 differentI2C addresses for the device.

The ADS112C04 is offered in a leadless 16-pin WQFN or a 16-pinTSSOP package and is specified over a temperature range of –40°C to +125°C.
