APDS-9700-020

Overview

The APDS-9700-020 is a signal conditioning integrated circuit designed for optical proximity sensors. Manufactured by Broadcom Limited, it operates within a supply voltage range of 3.3 V and consumes 500 uA of operating current. The component supports surface mount installation in a QFN-8 package. It functions across an extended temperature range from -40 C to +105 C. This device belongs to the APDS series and serves as a specialized interface for processing signals from external optical proximity sensing elements.

Feature Summary

• Provides dedicated signal conditioning for optical proximity sensor applications
• Supports surface mount technology with compact QFN-8 packaging
• Operates reliably across industrial temperature ranges

Applications

• Optical proximity detection systems
• Consumer electronics requiring proximity sensing interfaces
• Industrial control panels with optical safety features

Procurement Notes

Verify the specific manufacturer part number against official Broadcom documentation to ensure compatibility with your design requirements. Confirm that the QFN-8 package dimensions and pinout match your PCB layout specifications. Check for any recent product change notifications or lifecycle status updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing circuits that require dedicated signal conditioning for external optical proximity sensors rather than integrated light sensors. Ensure the system power supply aligns with the 3.3 V operating requirement. Verify that the thermal management strategy accommodates the specified -40 C to +105 C operating temperature range for the intended application environment.

Part Context

This component is part of Broadcom's APDS series, which focuses on sensor interface solutions. Unlike ambient light sensors or combined ALS/PS devices, this specific model targets the conditioning stage for discrete or separate optical proximity sensing elements. It represents a specialized interface solution within the broader portfolio of optical sensing components offered by the manufacturer.

Replacement Considerations

Consult official Broadcom documentation for verified substitute part numbers. Do not assume functional equivalence with other APDS series models without verifying pinouts and signal conditioning capabilities.
