Analog to Digital Converters

ADS1131IDR Description

The ADS1131IDR from Texas Instruments is a high-precision, 18-bit sigma-delta analog-to-digital converter (ADC) designed for demanding measurement applications. It features a single-channel differential input, ensuring accurate signal acquisition in noisy environments. The device operates with a supply voltage range of 3V to 5.3V for both analog and digital domains, making it versatile for various system designs. With an SPI-compatible serial interface, it seamlessly integrates into microcontroller-based systems. Packaged in a 16-pin SOIC and available in tape-and-reel (TR) format, the ADS1131IDR is optimized for surface-mount assembly and high-volume production. Its 80 samples per second (SPS) sampling rate balances resolution and speed for precision DC and low-frequency AC measurements.
