ADPD4001BCBZR7

Overview

The ADPD4001BCBZR7 is a multimodal analog front end from Analog Devices Inc. It features eight input channels and supports PPG, ECG, EDA, impedance, and temperature measurements. The device includes dual-channel processing with simultaneous sampling and twelve programmable time slots. It utilizes an I2C interface for data output and configuration. Key electrical parameters include a supply voltage range of 1.7 V to 1.9 V, a typical operating current of 10 µA, and a total system power dissipation of 50 µW under specific measurement conditions.

Feature Summary

• Supports multiple operation modes including photoplethysmography, electrocardiography, and bioimpedance.
• Features flexible input multiplexing for differential and single-ended sensor configurations.
• Integrates eight LED drivers capable of simultaneous activation for four channels.

Applications

• Wearable health and fitness monitors
• Industrial monitoring systems
• Home patient monitoring

Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and functional specifications before integration. Ensure that the I2C communication protocol requirements align with the host controller design. Review absolute maximum ratings to prevent damage during operation.

Selection Notes

Select this model when an I2C interface is required instead of SPI. Confirm that the application benefits from the integrated LED drivers and synchronous detection capabilities. Evaluate the power consumption constraints against the specified 50 µW system dissipation metric.

Part Context

This component belongs to the ADPD4000/ADPD4001 family of multimodal sensor front ends. It shares core functionality with the ADPD4000 but differs in its digital communication interface. The BCBZR7 suffix indicates the specific package type and reel packaging configuration provided by the manufacturer.

Replacement Considerations

The ADPD4000 serves as a direct alternative if SPI communication is preferred over I2C. Verify pin-to-pin compatibility and register map differences before substitution. Other members of the ADPD series may offer different channel counts or performance metrics.
