ADS1291IPBS TI Analog Front End | 32-TQFP (5x5) | 24-bit, 2-Channel, Low-Power

Product Overview

The ADS1291IPBS 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 oscillator. It is specifically designed for biopotential measurements such as ECG and EEG applications. The device operates from a single 2.7V to 5.25V supply and features a high common-mode rejection ratio (CMRR) of 110 dB, making it ideal for noisy environments. The ADS1291IPBS is housed in a compact 32-pin TQFP package (5x5 mm) and offers a flexible input multiplexer, lead-off detection, and a built-in test signal. Its low power consumption (0.75 mW/channel) and small footprint make it suitable for portable and battery-powered medical devices.
