The ADS1232/4 is a high-precision 24-bit Analog-to-Digital Converter (ADC), designed specifically for use with bridge sensors such as load cells, strain gauges, and pressure sensors. With an integrated low-noise programmable gain amplifier (PGA), a delta-sigma ADC with exceptional noise performance, and an onboard temperature sensor (ADS1232), the ADS1232/4 offers a complete solution for accurate and reliable sensor measurement.
Features:
- 24-bit resolution with up to 23.5 effective bits of accuracy for precise measurements.
- Low-noise programmable gain amplifier (PGA) with selectable gains of 1, 2, 64, and 128.
- RMS noise of 17nV at 10SPS and 44nV at 80SPS for clean data.
- Over 100 dB of 50Hz and 60Hz noise rejection for stable measurements in noisy environments.
- Built-in temperature sensor (ADS1232) for temperature monitoring.
- Flexible clocking options with a low-drift onboard oscillator (±3%) and optional external crystal.
- Easy ratiometric measurements with an external voltage reference up to 5V.
- Selectable data rates of 10SPS or 80SPS for different sampling needs.
- Two-channel differential input (ADS1232) or four-channel differential input (ADS1234).
- SPI interface for simple and reliable serial data transfer.
- Wide supply range of 2.7V to 5.3V for flexible system integration.
- Operating temperature range of -40°C to +105°C for industrial-grade reliability.
