ADS1131 Precision ADC



The Texas Instruments ADS1131 precision 18-bit ADC provides a complete front-end solution for bridge sensor applications

Texas Instruments ADS1131 Precision ADC Texas Instruments' ADS1131 is a precision, 18-bit analog-to-digital converter (ADC). With an onboard, low-noise amplifier, onboard oscillator, precision 18-bit delta-sigma (ΔΣ) ADC, and bridge power switch, the ADS1131 provides a complete 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. The ΔΣ ADC has 18-bit effective resolution and is comprised of a third-order modulator and fourth-order digital filter. Two data rates are supported: 10 SPS (with both 50 Hz and 60 Hz rejection) and 80 SPS.   ADS1131 Datasheet
