ADS1120IPW Description

Short technical summary and product information.

The Texas Instruments ADS1120IPW is a high-precision, 16-bit Analog-to-Digital Converter (ADC) designed for demanding measurement applications. It features a delta-sigma architecture, capable of sample rates up to 2 kSPS, with a noise-free resolution of 16 bits at 20SPS.

 

This ADC supports up to four single-ended or two differential input channels and includes an integrated Programmable Gain Amplifier (PGA) with gains from 1 to 128. It also features dual matched current sources for sensor excitation, an internal 2.048V reference with low drift, an internal temperature sensor, and simultaneous 50Hz/60Hz rejection.

 

The ADS1120IPW operates over a wide supply voltage range of 2.3V to 5.5V, with low power consumption as low as 120 µA typ in duty-cycle mode. It communicates via an SPI-compatible interface (mode 1).

 

Packaged in a 16-TSSOP, this component is designed for surface mounting. Its operating temperature range is -40°C to 125°C, making it suitable for various industrial and environmental conditions.
