Texas Instruments ADS1231

the ads1231 is a precision 24-bit analog-to-digital converter (adc). with an onboard low-noise amplifier onboard oscillator precision 24-bit delta-sigma () adc and bridge power switch the ads1231 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 128 supporting a full-scale differential input of 19.5mv. the adc has 24-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 ads1231 can be clocked by the internal oscillator or an external clock source. the ads1231 can be put in a low-power standby mode or shut off completely in power-down mode. view all in datasheet
