ADPD4000BCBZR7

Overview

The ADPD4000BCBZR7 is a multimodal sensor front end manufactured by Analog Devices Inc. It features an analog-to-digital converter with a 32-bit datapath width and a 256-byte FIFO buffer. The device supports SPI communication and operates on a supply voltage ranging from 1.7 V to 1.9 V, consuming 10 µA at 75 dB SNR. It provides eight input channels for simultaneous sampling and includes eight LED drivers capable of delivering up to 400 mA total current. The component functions within a temperature range of -40°C to +85°C and utilizes a 35-ball WLCSP package.

Feature Summary

• Supports multiple measurement modes including PPG, ECG, EDA, impedance, and temperature
• Features dual-channel processing with simultaneous sampling capability
• Includes flexible input multiplexing for differential and single-ended configurations
• Provides integrated ambient light rejection without external optical filters

Applications

• Wearable health monitors such as heart rate monitors and SpO2 sensors
• Industrial monitoring for CO, CO2, smoke, and aerosol detection
• Home patient monitoring systems

Procurement Notes

Verify the specific ordering suffix BCBZR7 against official documentation to confirm the 35-ball WLCSP package and reel packaging configuration. Ensure compatibility with the host system's SPI interface requirements and power supply constraints before finalizing procurement decisions.

Selection Notes

Select this component when a highly integrated solution for multimodal sensing is required. It is suitable for applications needing synchronous measurements of photodiodes, biopotential electrodes, and resistance sensors within a compact form factor.

Part Context

This part belongs to the ADPD4000/ADPD4001 series of multimodal sensor front ends. The ADPD4000 variant specifically utilizes an SPI interface for data output and configuration, distinguishing it from the I2C-based ADPD4001 model.

Replacement Considerations

The ADPD4001 serves as a functional alternative within the same family, offering identical performance but utilizing an I2C interface instead of SPI. Verify interface compatibility during substitution.
