ADS1294IPAG TI Analog Front End | 64-TQFP (10x10) | 4-Ch, 24-Bit, 8 kSPS

Product Overview

The ADS1294IPAG is a low-power, 4-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 high-performance, multi-channel data acquisition systems, it offers excellent noise performance and high common-mode rejection. The device operates from a single 5V supply and features a flexible input multiplexer per channel, making it ideal for biopotential measurements such as ECG, EEG, and EMG. The ADS1294IPAG is housed in a compact 64-pin TQFP (10x10 mm) package, enabling space-constrained designs.
