ADPD142RG-ACEZ-RL

Overview

The ADPD142RG-ACEZ-RL is a single-channel optical sensor integrated circuit manufactured by Analog Devices Inc. It integrates a green LED driver, photodiode, and analog front-end signal processing within an LFCSP package. The device operates on a supply voltage ranging from 2.7 V to 3.6 V with a typical operating current of 950 uA. Key electrical parameters include a rise time of 6 us and a fall time of 6 us. It supports I2C digital interface communication and functions within a temperature range of -40 C to +85 C.

Feature Summary

• Integrates green bandpass filter for optimized blood flow detection
• Combines LED driver, photodiode, and analog front-end in one package
• Supports digital I2C interface for simplified system integration

Applications

• Wearable health monitoring devices
• Smartwatch heart rate sensors
• Fitness tracking bands

Procurement Notes

Verify the specific suffix ACEZ-RL against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm end-of-life status or availability through authorized distributors prior to design finalization. Ensure component authenticity via manufacturer channels.

Selection Notes

Select this component when a compact, low-power solution for optical sensing is required. Compare against other ADPD series members for channel count and spectral filter options. Verify mechanical footprint compatibility with PCB layout constraints before procurement.

Part Context

This part belongs to the ADPD family of optical sensor ICs designed for biometric applications. It differs from multi-channel variants like the ADPD1080 by offering a single-channel configuration optimized for cost-sensitive wearable designs.

Replacement Considerations

Check Analog Devices documentation for direct pin-to-pin replacements within the ADPD series. Consider ADPD1080 for dual-channel needs or ADPD188BI for different spectral requirements.
