ADS1294RIZXGR TI Analog Front End | 64-NFBGA (8x8) | 4-Ch, 24-Bit, 250kSPS

Product Overview

The ADS1294RIZXGR is a low-power, 4-channel, 24-bit delta-sigma analog front-end (AFE) from Texas Instruments, designed for biopotential measurements such as ECG and EEG. It integrates programmable gain amplifiers (PGAs), internal reference, and an oscillator, reducing component count and board space. The device operates from a single 2.7V to 5.25V supply and features a data rate up to 250kSPS. Housed in a compact 64-ball NFBGA (8x8mm) package, it is ideal for portable and high-channel-count medical systems.
