ADAS1000-4BCPZ-RL

Overview

The ADAS1000-4BCPZ-RL is a low-power, three-electrode electrocardiogram (ECG) analog front end manufactured by Analog Devices Inc. It features three acquisition channels and one driven lead, supporting AC and DC lead-off detection along with an internal pace detection algorithm. The device measures ECG signals, thoracic impedance, pacing artifacts, and lead status, outputting digitized data via a serial interface. It operates within a supply voltage range of 3.15 V to 5.5 V for AVDD and 1.65 V to 3.6 V for IOVDD. Key electrical parameters include a signal-to-noise ratio of 100 dB, input referred noise as low as 6 μV p-p in analog lead mode, and power dissipation ranging from 11 mW to 29.7 mW depending on configuration.

Feature Summary

• Three ECG acquisition channels with integrated right leg drive and selectable reference lead
• Internal pace detection algorithm operating on all three leads with support for user-defined algorithms
• Thoracic impedance measurement capability using internal or external paths
• Scalable noise versus power control architecture allowing channel shutdown and data rate reduction

Applications

• Bedside patient monitoring systems
• Portable telemetry and Holter monitors
• Automated external defibrillators (AED)
• Cardiac defibrillators and ambulatory monitors

Procurement Notes

Verify the specific ordering suffix BCPZ-RL against the manufacturer's current datasheet to confirm package type and reel specifications. Ensure compatibility with system power rails, specifically the 3.3 V analog supply and 1.8 V digital domains. Confirm that the 56-lead LFCSP footprint matches the design layout requirements.

Selection Notes

Select the ADAS1000-4 over the ADAS1000-3 when respiration and pace detection features are required. Consider the 56-lead LFCSP package for space-constrained designs compared to the 64-lead LQFP option. Evaluate power consumption requirements, as the device supports low-power modes suitable for battery-operated applications.

Part Context

The ADAS1000-4 is part of the ADAS1000 family of biopotential analog front ends designed for high-performance ECG applications. It complements other variants like the ADAS1000 and ADAS1000-1, which offer five channels. The device is specified for operation between −40°C and +85°C, targeting both diagnostic and monitoring medical equipment.
