ADAS1000-3BCPZ

Overview

The ADAS1000-3BCPZ 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, designed for biopotential signal digitization. The device supports AC and DC lead-off detection and includes an internal pace detection algorithm on all three leads. It offers scalable noise versus power control and fast overload recovery. Electrical specifications include a supply voltage range of 3.15 V to 5.5 V for AVDD and 1.65 V to 3.6 V for IOVDD. Power dissipation is rated at 15 mW with three leads enabled in high-performance mode. The component is housed in a 56-lead LFCSP package.

Feature Summary

• Three ECG acquisition channels with integrated right leg drive and shield driver
• Internal pace detection algorithm operating on three leads
• Scalable noise vs. power architecture allowing channel shutdown and data rate reduction
• AC and DC lead-off detection capabilities

Applications

• ECG monitor and diagnostic systems
• Bedside patient monitoring and portable telemetry
• Holter monitors and ambulatory cardiac monitors
• Automated external defibrillators (AED) and cardiac defibrillators
• Patient transport and stress testing equipment

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 56-lead LFCSP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors prior to procurement. Ensure availability matches project timelines as supply levels may fluctuate.

Selection Notes

Select the ADAS1000-3BCPZ over the ADAS1000-4 model if respiration measurement and dedicated pace detection hardware are not required, as the -3 variant omits these features. Choose this part for applications requiring three-channel ECG acquisition with lower power consumption compared to five-channel alternatives. Ensure the system design accommodates the 56-lead LFCSP footprint.

Part Context

This component belongs to the ADAS1000 series of analog front ends designed for biopotential applications. It serves as a primary or secondary device within multi-chip configurations to expand electrode counts. The ADAS1000-3 specifically targets cost-sensitive or space-constrained designs where only three ECG channels are necessary, distinguishing it from the feature-rich ADAS1000-4.

Replacement Considerations

The ADAS1000-4BCPZ is a compatible substitute offering identical pinout and form factor but adds respiration and pace detection features. The ADAS1000BCPZ provides five channels instead of three. Verify register compatibility and software adjustments when migrating between these variants.
