Table 1: Added value of using AS7058

Benefits

Features

Highly flexible LED/photodiode configuration.

Up to 8 LED output pins and 8 photodiode input pins.

Allows the smallest application size e.g. narrow HRM

measurement band.

Small Wafer-Level-Chip-Scale-Package (WLCSP).

Electrocardiogram (ECG) with dry electrodes.

Embedded low-noise analog front-end for ECG signal

acquisition.

Enables blood pressure measurements.

Synchronized PPG and ECG acquisition.

Outstanding HRM measurement quality.

Low noise analog front end for PPG acquisition.

Measuring the body composition and the skin’s water

content.

An independent body impedance and an electrodermal

activity system are included.

Long operating time.

A hardware sequencer to offload the processor with an

adjustable LED driver with current control.

Low power operating mode.

Two PPG channels usable in parallel mode are

available.

Acquiring several bio signals in parallel.

Either ECG, BIOZ or EDA (GSR) and two PPG

channels, separated and usable simultaneously.

Improvement in ambient light suppression.

Includes a new type of offset cancelation for the PPG

signal: Advanced Automatic Offset Control.
