The device features two differential or four single-ended inputs through a flexible input multiplexer (MUX), two programmable excitation current sources, programmable gain amplifier (PGA), a voltage reference, a clock oscillator, and a precision temperature sensor.
It offers two conversion modes — single-shot or continuous — and can perform conversions at data rates up to 2,000 samples-per-second (SPS) with single cycle settling.
At 20 SPS, the device’s digital filter offers simultaneous 50-Hz and 60-Hz rejection for noisy industrial applications.
The ADS112C04 features a Two Wire, I2C-compatible interface that supports I2C bus speeds up to 1 Mbit per second (Mbps), with two address pins that allow selection of 16 different I2C addresses for the device.
The 5.0 mm × 4.40 mm TSSOP device operates from a wide supply range of 2.3V to 5.5V over a temperature range of minus 40 to 125 degrees Celsius.
Also available is the ADS112C04EVM evaluation kit and Delta-Sigma ADC EvaluaTIon Software.
