ADPD142RI-ACEZ-RL

Overview

The ADPD142RI-ACEZ-RL is a photoplethysmography (PPG) optical sensor module manufactured by Analog Devices Inc. It integrates red and infrared light emitters with an analog front-end for bio-sensing applications. The device operates on a single supply voltage ranging from 2.7 V to 3.6 V, consuming typical current of 10 mA during active operation. It features a serial peripheral interface (SPI) for configuration and data readout. The component is housed in a compact 8-lead leadless chip carrier package designed for surface-mount technology, suitable for space-constrained wearable health monitoring devices.

Feature Summary

• Integrated optical sensing solution combining emitters and detection circuitry
• Supports multi-wavelength PPG measurements using red and infrared LEDs
• Low power consumption optimized for battery-operated portable systems

Applications

• Wearable heart rate monitors
• Pulse oximetry sensors
• Bio-sensing modules for fitness trackers

Procurement Notes

Verify the specific suffix ACEZ against official Analog Devices documentation to confirm RoHS compliance and tape-and-reel packaging specifications. Confirm end-of-life status or availability through authorized distributors, as lifecycle notifications may affect long-term procurement planning.

Selection Notes

Select this module when a compact, integrated optical front-end is required for pulse oximetry or heart rate monitoring. Ensure the system design supports the 2.7 V to 3.6 V operating range and accommodates the SPI communication protocol for control and data acquisition.

Part Context

This component belongs to the ADPD series of optical sensor modules from Analog Devices. These devices are engineered specifically for non-invasive physiological monitoring, integrating LED drivers and photodiode amplifiers into a single small form factor to simplify PCB layout for wearable electronics.

Replacement Considerations

Consult Analog Devices technical support for verified cross-reference part numbers. Evaluate alternative ADPD family members based on channel count and emitter integration requirements before substitution.
