Description
Integrated Circuits ADS1231IDR Texas Instruments IC ADC 24BIT SIGMA-DELTA
The ADS1231 is a high-precision, 24-bit analog-to-digital converter (ADC) designed specifically for bridge sensor applications. It features an integrated low-noise internal amplifier with a gain of 128, an onboard oscillator, and a precision third-order delta-sigma (ĪĪ£) modulator, along with a low-side power switch for bridge sensors.
This comprehensive front-end solution is suitable for various applications, including weigh scales, strain gauges, and load cells. The device supports selectable data rates of 10SPS or 80SPS. The low-noise amplifier, with a gain of 128, is capable of handling a full-scale differential input of Ā±19.5mV while providing simultaneous rejection of both 50Hz and 60Hz signals.
The ĪĪ£ ADC operates at 10SPS with a resolution of 24 bits and includes a third-order modulator and a fourth-order digital filter. It supports two data rates: 10SPS (with rejection for both 50Hz and 60Hz) and 80SPS. The ADS1231 can be placed in a low-power standby mode or completely powered down. Control of the ADS1231 is achieved through dedicated pins, eliminating the need for digital register programming. Data output is facilitated via a simple, isolated serial interface that connects directly to the MSP430 and other microcontrollers.
The supply voltage range for the ADS1231 is from 3V to 5.3V, and it is packaged in an SOIC-16 format. The operating temperature range is specified from ā40Ā°C to +85Ā°C. APPLICATIONS
