ADS1293CISQE/NOPB TI Analog Front End | 28-WQFN (5x5) | 3-Ch, 24-Bit ADC

Product Overview

The ADS1293CISQE/NOPB is a low-power, 3-channel, 24-bit delta-sigma analog-to-digital converter (ADC) with integrated programmable gain amplifier (PGA), reference, and 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. It communicates via SPI interface and is available in a compact 28-pin WQFN package (5x5 mm).
