ADAS1000BCPZ

Overview

The ADAS1000BCPZ is a low-power, five-electrode electrocardiogram (ECG) analog front end from Analog Devices. It measures biopotential signals including ECG data, thoracic impedance, pacing artifacts, and lead-on/lead-off status. The device features five acquisition channels with one driven lead, supporting AC and DC lead-off detection and an internal pace detection algorithm on three leads. It offers scalable noise versus power control and fast overload recovery. Electrical specifications include a 3.15 V to 5.5 V AVDD supply range, 1.71 V to 1.89 V for ADCVDD and DVDD, and a 1.65 V to 3.6 V IOVDD range. Resolution reaches 19 bits at 2 kHz data rates. The component is housed in a 56-lead LFCSP package.

Feature Summary

• Five-channel ECG acquisition with integrated respiration measurement and pace detection algorithms
• Supports AAMI EC11, IEC60601-1, and other medical standards compliance
• Scalable noise-to-power architecture allowing optimization for battery life or signal fidelity
• Integrated calibration DAC and test tone generation for manufacturing verification

Applications

• Bedside patient monitoring systems
• Portable telemetry and Holter monitors
• Automated external defibrillators (AED)
• Cardiac defibrillators and ambulatory monitors
• Pacemaker programmers and stress testing equipment

Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's current ordering guide to confirm package type and temperature grade. Ensure compatibility with the required SPI/QSPI/DSP interface timing parameters for the target system design.

Selection Notes

Select this model when full diagnostic features including respiration and pace detection are required. For applications needing only basic ECG channels without respiration or pace functions, consider the ADAS1000-1 variant. Use the ADAS1000-2 as a secondary companion chip to expand channel counts beyond five electrodes.

Part Context

This component belongs to the ADAS1000 series of biopotential analog front ends designed for cardiac monitoring. The series includes variants like the ADAS1000-1 and ADAS1000-2 to address different feature sets and gang-mode configurations for multi-electrode systems.
