ADS1131 Description
The ADS1131 is a precision, 18-bit analog-to-digital converter (ADC). With an onboard, low-noise amplifier, onboard oscillator, precision 18-bit deltasigma (ΔΣ) ADC, and bridge power switch, the ADS1131 provides a plete front-end solution for bridge sensor applications including weigh scales, strain gauges, and load cells. The low-noise amplifier has a gain of 64, supporting a full-scale differential input of ±39mV.
