Texas Instruments ADS112C04 16-Bit Low-Power ADCs

Texas Instruments ADS112C04 16-Bit Low-Power ADCs provide four channels, low-power, 2 IDACs, and an I²C interface. Many features are integrated, reducing system cost and component count in applications that measure small sensor signals. Additionally, the PGA offers gains up to 128 making the ADS112C04 ideal for applications such as resistance temperature detectors (RTDs), thermocouples, thermistors, and resistive bridge sensors. The I²C-compatible interface provides 2-wire connectivity and supports up to 1Mbps bus speeds. Other features on the device include a precision temperature sensor, an oscillator, a voltage reference, a programmable gain amplifier (PGA), and two differential or four single-ended inputs through a flexible input multiplexer (MUX). Conversion data rates are performed at up to 2000 samples-per-second (SPS) with single-cycle settling. The digital filter performs simultaneous 50Hz and 60Hz rejections for noisy industrial applications at 20SPS. The Texas Instruments ADS112C04 is specified over a temperature range of –40°C to +125°C.
