ADPD7000BCBZR7

Overview

The ADPD7000BCBZR7 is a multimodal analog front end (AFE) from Analog Devices, packaged in a 36-ball WLCSP. It integrates four input channels with simultaneous sampling capability and supports up to eight LED drivers for optical measurements. The device features dedicated signal chains for electrocardiography (ECG), body impedance analysis (BIA), and electrodermal activity (EDA). Key electrical parameters include an operating voltage range of 1.7 V to 3.6 V, a 32-bit data path width, and a 704-byte FIFO. It operates within a temperature range of -40°C to +85°C and utilizes an SPI interface for configuration.

Feature Summary

• Multimodal AFE supporting PPG, ECG, BIA, and EDA measurements with 4-channel simultaneous sampling
• Optical transceiver with 8 LED drivers (up to 400 mA total peak current) and AC ambient light rejection up to 100 Hz
• ECG channel with <1 µV RMS RTI noise at diagnostic bandwidth and 115 dB CMRR
• Integrated BIA excitation path with configurable frequency up to 250 kHz and complex impedance measurement engine

Applications

• Wearable health monitors for heart rate, pulse oximetry, and body impedance analysis
• Clinical patient monitors including bed-side and portable units
• Industrial monitoring for particle, aerosol, and gas detection
• Conductivity detection systems

Procurement Notes

Verify the specific ordering suffix BCBZR7 against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required supply voltages (AVDD, DVDD, IOVDD) and check for any regional distribution restrictions or lead time updates directly from authorized suppliers.

Selection Notes

Select this component when a single chip must handle multiple vital sign modalities including optical, electrical, and bioimpedance sensing. Consider the 36-ball WLCSP package constraints for PCB layout and thermal management. Verify that the host system can support the SPI interface timing requirements and provides the necessary power rails for the integrated LED drivers and analog sections.

Part Context

The ADPD7000BCBZR7 belongs to the ADPD7000 series of multimodal sensor front ends. It is designed as a highly integrated solution for wearable devices, replacing discrete components typically used for PPG, ECG, and BIA signal conditioning. The part is often evaluated using the EVAL-ADPD7000Z demonstration kit.
