ADS1131IDR Description

Short technical summary and product information.

The ADS1131IDR from Texas Instruments is a high-precision, 18-bit analog-to-digital converter (ADC) specifically engineered for resistive bridge sensor applications such as weigh scales, strain gauges, and load cells. This delta-sigma ADC offers a single differential input channel and operates at a maximum sample rate of 80 SPS.

 

Key electrical characteristics include an 18-bit resolution, an SPI interface for digital communication, and a wide analog supply voltage range of 3V to 5.3V. The device also features a selectable 50/60 Hz rejection, an onboard oscillator, and a programmable gain amplifier (PGA). The input voltage range is specified from 0V to 0.041V.

 

Packaged in a 16-SOIC format, the ADS1131IDR is designed for surface mount applications. It operates within an industrial temperature range of -40°C to 85°C. The integrated low-noise amplifier and bridge power switch simplify the front-end design for bridge sensor systems.
