ADPD6000BCBZR7

Overview

The ADPD6000BCBZR7 is a multimodal analog front end (AFE) from Analog Devices, packaged in a 36-ball wafer level chip scale package (WLCSP). It integrates optical, ECG, and body impedance analysis (BIA) signal chains. Key electrical parameters include a 32-bit data path width, a 640-byte FIFO, and an SPI interface with a maximum clock frequency of 10 MHz. The device operates on AVDD (1.7 V to 1.9 V), DVDD (1.7 V to 1.9 V), and IOVDD (1.7 V to 3.6 V). It supports sampling rates from 0.004 Hz to 9 kHz and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Optical Channel: Supports up to four LEDs and four current inputs with simultaneous dual-channel processing, 12 programmable time slots, and AC ambient light rejection up to 78 dB at 100 Hz.
• ECG Channel: Provides diagnostic-level measurement with 0.75 μV rms input-referred noise at 150 Hz bandwidth, 3 GΩ input impedance, and integrated DC/AC lead-off detection.
• BIA Channel: Features a low-power excitation path with a 12-bit DAC for sine wave generation up to 250 kHz, supporting complex impedance measurement with internal calibration.
• System Integration: Includes flexible LED drivers with a total peak current of 400 mA, digital filters, and SPI communication for configuration and data output.

Applications

• Wearable health and fitness monitors including heart rate, SpO2, and body impedance analysis
• Home patient monitoring systems
• Industrial monitoring for particle, aerosol, gas, and conductivity detection

Procurement Notes

Verify the specific ordering suffix BCBZR7 against the manufacturer's official documentation to confirm packaging details such as reel quantity or tape-and-reel specifications. Ensure that the required voltage levels for AVDD, DVDD, and IOVDD are compatible with the target system design before procurement.

Selection Notes

Select this component when a single AFE must handle multimodal sensing tasks including photoplethysmography, electrocardiography, and bioimpedance. Consider the 2.6 mm × 2.6 mm WLCSP package constraints for PCB layout. Verify that the host microcontroller supports the required SPI timing specifications and can manage the 640-byte FIFO buffer effectively.

Part Context

The ADPD6000BCBZR7 belongs to the ADPD6000 family of multimodal sensor front ends. It is designed to replace discrete solutions by integrating multiple signal chains into one highly compact package. The EVAL-ADPD6000Z evaluation board is available for testing and development purposes.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Consult the manufacturer's documentation for potential cross-reference options or updated revisions.
