ADAS1000-1BCPZ-RL

Overview

The ADAS1000-1BCPZ-RL is a five-channel electrocardiogram (ECG) analog front end manufactured by Analog Devices Inc. It measures cardiac signals and outputs digitized data via an SPI-compatible serial interface. The device features 56-lead LFCSP packaging with dimensions of 9 mm × 9 mm. Electrical specifications include a supply voltage range of 3.15 V to 5.5 V for AVDD, and 1.71 V to 1.89 V for ADCVDD and DVDD. It operates at programmable data rates up to 128 kHz with a resolution of 19 bits at 2 kHz or 18 bits at 16 kHz. Power consumption reaches 41 mW in high-performance mode with all channels enabled.

Feature Summary

• Five dedicated ECG acquisition channels with internal right leg drive and shield driver capabilities.
• Supports AC and DC lead-off detection algorithms for electrode contact verification.
• Integrated calibration DAC and test tone generation for manufacturing and system diagnostics.
• Scalable noise versus power architecture allowing configurable performance modes.

Applications

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

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing components. Confirm that the ADAS1000-1 variant lacks respiration and pace detection features compared to the standard ADAS1000 model. Ensure compatibility with the required 56-lead LFCSP footprint during procurement planning.

Selection Notes

Select the ADAS1000-1BCPZ-RL when only ECG signal acquisition is required without respiration or pacing analysis. This model serves as a primary device supporting secondary companion chips like the ADAS1000-2 for expanded channel counts. Verify that the application does not require the internal pace detection algorithm present in the full ADAS1000 version.

Part Context

This component belongs to the ADAS1000 family of biopotential analog front ends designed for cardiac monitoring. The ADAS1000-1 is a subset of the main ADAS1000 device, retaining the five ECG channels and right leg drive but excluding respiration measurement and internal pace detection functions found in the primary model.

Replacement Considerations

The ADAS1000BCPZ-RL is a compatible alternative within the same family, offering additional respiration and pace detection features. The ADAS1000-2BCPZ-RL serves as a secondary companion device rather than a direct standalone replacement.
