Descripción de ADS1231
The ADS1231 is a precision, 24-bit analog-to-digital converter (ADC). 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. Two data rates are supported: 10SPS (with both 50Hz and 60Hz rejection) and 80SPS. The ADS1231 can be put in a low-power standby mode or shut off completely in power-down mode.
The ADS1231 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.
The ADS1231 is available in an SO-16 package and is specified from –40°C to +85°C.
