AS7058-BWLT WLP LF T&R

Analog Front End (AFE) Overview

The AS7058-BWLT is an Analog Front End (AFE) biosignal sensor manufactured by ams OSRAM. It integrates three analog-to-digital converters with 20-bit resolution and operates at a supply voltage of 1.8V. The component is housed in a 42-pin Wafer Level Chip Scale Package (WLCSP). This configuration supports compact form factors for wearable health monitoring applications.

Analog Front End (AFE) Feature Summary

• Integrates photoplethysmogram, electrocardiogram, and body impedance measurement capabilities within a single device.
• Enables blood pressure estimation through integrated physiological signal processing features.
• Supports electrocardiogram acquisition using dry electrode configurations for simplified interface design.

Analog Front End (AFE) Applications

• Heart rate monitoring band applications
• Electrocardiogram devices utilizing dry electrodes
• Blood pressure measurement systems
• Body composition analysis in wearable devices

Analog Front End (AFE) Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Ensure the supplier provides valid traceability documentation for the WLCSP package. Check for any recent product change notifications regarding substrate or assembly partner transfers that may affect long-term availability.

Analog Front End (AFE) Selection Notes

Select this component when designing multi-vital sign monitors requiring high-resolution biosignal acquisition. The 20-bit ADC resolution suits low-amplitude physiological signals. The 42-pin WLCSP package minimizes board space for narrow bands. Consider the 1.8V operating voltage for compatibility with low-power mobile processors.
