ADS1231 Datasheet PDF

●The ADS1231ID is a 24-bit Analogue-to-digital Converter with an onboard low-noise amplifier, onboard oscillator, precision third-order 24-bit delta-sigma modulator 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 resolution and is comprised of a third-order modulator and fourth-order digital filter. Supports 80SPS of data rate and can be put in a low-power standby mode or shut off completely in power-down mode. This ADC is controlled by dedicated pins, there are no digital registers to program. Data are output over an easily-isolated serial interface that connects directly to the MSP430 and other microcontrollers.
