ADS1291IRSMR TI Analog Front End | 32-VQFN (4x4) | 24-bit, 2-Channel, Low-Power

Product Overview

The ADS1291IRSMR is a low-power, 2-channel, 24-bit delta-sigma (ΔΣ) analog-to-digital converter (ADC) with integrated programmable gain amplifier (PGA), internal reference, and an onboard oscillator. Designed for biopotential measurements, it offers high resolution and low noise, making it ideal for medical instrumentation such as ECG, EEG, and patient monitoring systems. The device operates from a single 2.7V to 5.25V supply and features a flexible input multiplexer, lead-off detection, and a built-in test signal. Housed in a compact 32-VQFN (4x4 mm) package, it enables space-constrained designs.
