Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Request official datasheets and test reports to confirm specifications match the ADPD142RI-ACEZ-R7 designation. Ensure storage conditions comply with moisture sensitivity levels to prevent package damage prior to assembly.

Selection Notes

Select this module when integrated red and infrared optical sources are required for PPG sensing. Consider the specific package dimensions and I2C interface compatibility with the target microcontroller. Evaluate power consumption requirements against the 9.3 mA operating current to ensure battery life targets are met in portable designs.

Part Context

This component belongs to the ADPD series of optical sensor modules from Analog Devices. These modules typically combine front-end electronics with optical elements to simplify the design of biometric sensing systems. The RI suffix indicates the specific wavelength configuration and packaging variant within the product family.

Replacement Considerations

Consult Analog Devices documentation for direct pin-to-pin replacements or functional equivalents within the ADPD series. Verify that any substitute part maintains identical optical wavelengths, package footprint, and I2C register compatibility before implementation.
