ADS1261BQWRHMRQ1 TI Analog-to-Digital Converter | 32-VQFN (5x5) | 24-Bit, 40 kSPS

Product Overview

The ADS1261BQWRHMRQ1 is a precision, 24-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) from Texas Instruments. It offers a maximum data rate of 40 kSPS and integrates a programmable gain amplifier (PGA), voltage reference, and oscillator. Housed in a compact 32-VQFN (5x5 mm) package, this device is designed for high-accuracy measurement applications in automotive and industrial environments. Its low noise (4.7 µVpp at 20 SPS) and high linearity make it ideal for sensor signal conditioning, including thermocouples, RTDs, and pressure sensors.
