ADAS1000BCPZ-RL

Overview

The ADAS1000BCPZ-RL is a low-power, five-electrode electrocardiogram (ECG) analog front end manufactured by Analog Devices Inc. It measures biopotential signals including ECG, thoracic impedance, pacing artifacts, and lead-on/lead-off status, outputting digitized data via an SPI-compatible serial interface. The device features five acquisition channels with selectable gain settings (×1.4 to ×4.2), internal pace detection algorithms, and AC/DC lead-off detection. It operates on AVDD supplies ranging from 3.15 V to 5.5 V and digital supplies of 1.8 V. Key electrical parameters include a 24-bit resolution, up to 2 MS/s sampling rate, and a signal-to-noise ratio of 100 dB. Power consumption ranges from 11 mW for single-lead operation to 41 mW with all channels enabled in high-performance mode.

Feature Summary

• Five-channel ECG acquisition with integrated respiration measurement and internal pace detection algorithms.
• Supports AAMI EC11, IEC60601-1, and other medical standards with fast overload recovery.
• Scalable noise versus power control architecture allowing configurable performance modes.
• Integrated calibration DAC, shield driver, and driven right leg amplifier for signal integrity.

Applications

• Diagnostic and monitoring ECG systems
• Bedside patient monitors and portable telemetry devices
• Holter monitors and ambulatory cardiac monitors
• Automated external defibrillators (AED) and cardiac defibrillators

Procurement Notes

Verify the ordering suffix -RL indicates reel packaging when sourcing components. Confirm that the LFCSP-56 package variant matches the specific design requirements for thermal resistance and pin compatibility. Ensure supply voltages align with the specified 3.15 V to 5.5 V range for AVDD and 1.8 V for digital domains.

Selection Notes

Select the ADAS1000BCPZ-RL for applications requiring integrated respiration and pace detection alongside standard ECG channels. Consider the ADAS1000-1 if respiration and pace features are unnecessary, or the ADAS1000-2 for secondary gang-mode expansion. Evaluate power constraints against the high-performance and low-power modes available through the scalable architecture.

Part Context

This component belongs to the ADAS1000 family of biopotential analog front ends. The BC designation typically indicates industrial temperature range specifications (-40°C to +85°C). The part is designed to simplify ECG signal acquisition by integrating amplification, filtering, and ADC functions into a single small-footprint package.

Replacement Considerations

Direct replacements within the same family include ADAS1000BCPZ for tray packaging or ADAS1000-1BCPZ-RL if respiration and pace features are not required. For expanded channel counts, the ADAS1000-2 series can be used in conjunction with primary devices in gang mode.

FAQ

What is the maximum sampling rate supported by the ADAS1000?

The device supports programmable data rates up to 128 kHz for digital output frames, with typical ECG operations running at 2 kHz or 16 kHz.

Does the ADAS1000 support internal pace detection?

Yes, the ADAS1000 model includes an internal pace detection algorithm operating on three leads. The ADAS1000-1 variant does not include this feature.

What is the input common-mode voltage range?

The common-mode input voltage range is typically 0.3 V to 2.3 V, independent of the supply voltage, centered around the internal VCM_REF of approximately 1.3 V.
