The ADPD144RI-ACEZ-RL7 is a photometric front end module from Analog Devices, designed for photoplethysmography (PPG) detection of blood oxygenation (SpO2). It integrates red and infrared LED emitters, a 4-channel photodiode, and a custom ASIC with AFE, ADC, LED drivers, and timing core in a compact 12-LFLGA package.
The module operates from a supply voltage of 1.7V to 4.3V and draws a typical supply current of 9.3 mA. It provides a 14-bit ADC resolution and communicates via an I2C interface. The red LED has a wavelength of 660 nm and the IR LED has a wavelength of 880 nm. The operating temperature range is -40°C to +85°C.
The ADPD144RI is specifically designed for optical heart rate monitoring and reflective SpO2 measurement. Its synchronous detection scheme rejects ambient light interference, making it suitable for wearable and medical devices. The module is surface-mountable and comes in a 12-LGA-CAV (2.8x5) package.
The supply voltage range is 1.7V to 4.3V.
The part is available in a 12-LFLGA surface mount package, also specified as 12-LGA-CAV (2.8x5).
The operating temperature range is -40°C to +85°C.
The part is marked as RoHS3 compliant, but this status is unverified.
The module uses an I2C interface for data and control.
The ADC resolution is 14 bits.
The module has 4 photodiode channels.
