ADPD174GGI-ACEZRL

Overview

The ADPD174GGI is an integrated optical module designed for photometric signal measurement with ambient light rejection. It houses a custom package containing two green LEDs, one infrared LED, and a single photodiode. The internal ASIC features a 14-bit ADC with a 20-bit burst accumulator and three independently configurable 250 mA LED drivers. Data output and configuration are managed via a 1.8 V I²C interface. The module dimensions are 2.8 mm × 6.5 mm.

Feature Summary

Integrated optical components: 2 green LEDs, 1 IR LED, and 1 photodiode in a 2.8 mm × 6.5 mm package
Three-channel true 250 mA LED driver with separate settings per channel
14-bit ADC with 20-bit burst accumulator enabling 20 bits per sample period
On-board sample-to-sample accumulator supporting up to 27 bits per data read

Applications

Optical heart rate monitoring
Reflective SpO2 measurement

Procurement Notes

Verify the specific ordering suffix ACEZRL against official Analog Devices documentation to confirm reel packaging and tape specifications. Ensure compatibility with 1.8 V I²C logic levels during system integration. Cross-reference the datasheet revision SpA for any updates to electrical characteristics or pin configurations before finalizing procurement.

Selection Notes

Select this component for applications requiring synchronous detection to reject ambient light interference. The 27-bit effective resolution via on-board accumulation is suitable for signal-limited cases. Verify that the 2.8 mm × 6.5 mm form factor fits the mechanical constraints of the target device. Confirm that the 250 mA LED drive capability meets the optical power requirements for the intended sensing distance.

Part Context

The ADPD174GGI belongs to the ADPD174 family of integrated optical modules. It is specifically engineered for reflective pulse oximetry and heart rate monitoring where compact size and high signal integrity are critical. The design integrates the photometric front end, control logic, and LED drivers into a single unit to simplify PCB layout.
