AS7058A-BWLM

Analog Front End (AFE) Overview

The AS7058A-BWLM is an integrated analog front-end (AFE) manufactured by ams OSRAM, designed for comprehensive multi-vital sign monitoring. This device consolidates signal acquisition capabilities for photoplethysmography (PPG), electrocardiogram (ECG), bioimpedance (BioZ), and electrodermal activity (EDA). It enables the measurement of pulse rate, blood oxygen levels via vascular light modulation, cardiac bioelectric signals, skin moisture content, and body composition analysis through electronic impedance systems.
