ADS122C04IPW Description

Short technical summary and product information.

The ADS122C04IPW is a 24-bit, 2-kSPS, 4-channel delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It integrates a programmable gain amplifier (PGA), voltage reference, oscillator, temperature sensor, and dual programmable current sources (iDACs). The device supports both differential and single-ended inputs, with a configuration of two differential or four single-ended channels.

 

The ADC offers programmable gain from 1 to 128, an internal 2.048-V reference with 5 ppm/°C drift, and an internal oscillator with 2% accuracy. Analog and digital supply voltages range from 2.3 V to 5.5 V, with typical power consumption of 1.4 mW and current consumption of 315 µA. The operating temperature range is -40°C to 125°C.

 

Data is transferred via an I2C interface supporting standard, fast, and fast-mode plus speeds, with up to 16 pin-configurable addresses. The device includes 50/60 Hz rejection for mains noise, making it suitable for sensor measurement in industrial and process control applications. It is available in a 16-pin TSSOP package measuring 5 mm × 6.4 mm.
