Description
The ADS131A04IPBS is a 24-bit, 4-channel, delta-sigma analog-to-digital converter (ADC) from Texas Instruments, designed for high-precision measurement applications. It features low noise (4.2 µVrms at 1 kSPS), high accuracy, and a flexible input range (±2.5V or ±1.25V differential).
Key features include:
- 4 simultaneous sampling channels with built-in programmable gain amplifiers (PGA).
- SPI interface for communication with microcontrollers.
- Low power consumption (3.5 mW per channel at 1 kSPS).
- Integrated diagnostics for system monitoring.
Ideal for industrial, medical, and energy monitoring systems, the ADS131A04IPBS offers excellent performance in noisy environments due to its high common-mode rejection ratio (CMRR). It operates from a single 3.3V or 5V supply and comes in a 32-pin TQFP (PB) package.
Applications include:
- Power metering
- ECG/EEG equipment
- Industrial sensors
Its compact design and robust performance make it a reliable choice for precision data acquisition.
