ADS131A04IPBSR

The ADS131A04IPBSR is a 24-bit, 4-channel, simultaneous-sampling delta-sigma (ΔΣ) analog-to-digital converter (ADC) from Texas Instruments. Designed for precision measurements, it features low noise, high accuracy, and a flexible input range (±2.5V or ±1.25V).
Key features:
- 4 simultaneous channels at up to 64 kSPS per channel.
- Low power: 3.5 mW/channel at 32 kSPS.
- Integrated PGA (programmable gain amplifier) with gains from 1 to 128.
- SPI-compatible interface for easy microcontroller communication.
- Built-in diagnostics (open/short detection, CRC).
Applications include industrial sensors, power monitoring, medical devices, and energy metering. The IPBSR package is a 32-pin TQFP, suitable for compact designs.
Its high resolution and low noise make it ideal for demanding signal acquisition tasks.
