AFE4420YZR

Analog Front End (AFE) Overview

The AFE4420YZR is an ultra-small, integrated analog front-end (AFE) designed for multi-sensor wearable devices. It features a 24-bit resolution and supports four channels. The device integrates a first-in-first-out (FIFO) buffer to facilitate efficient data handling in optical heart-rate monitoring and bio-sensing applications. Manufactured by Texas Instruments, it operates within a surface-mount DSBGA-30 package. The component is part of the AFE4420 series, optimized for low-power biometric sensing systems requiring high precision and compact form factors.
