ADS1131 18-bit Analog-to-Digital Converter (ADC)

Texas Instruments ADS1131 18-bit Analog-to-Digital Converter for Bridge Sensors is a precision delta-sigma ADC that provides a complete front-end solution for bridge sensor applications, including weigh scales, strain gauges, and load cells. The TI ADS1131 features an onboard low-noise amplifier with a gain of 64, supporting a full-scale differential input of ±39mV. The ADS1131 delta-sigma ADC has an 18-bit effective resolution and is comprised of a third-order modulator and fourth-order digital filter. Two data rates are supported: 10SPS (with both 50Hz and 60Hz rejection) and 80SPS. The Texas Instruments ADS1131 can be put into a low-power standby mode or shut off completely in power-down mode.
