ADAS1000-1BCPZ

Overview

The ADAS1000-1BCPZ is a five-channel electrocardiogram (ECG) analog front end from Analog Devices, housed in a 56-lead LFCSP package. It provides biopotential signal acquisition with 19-bit resolution at 2 kHz and 18-bit resolution at 16 kHz data rates. The device supports AVDD supply voltages between 3.15 V and 5.5 V, with ADCVDD and DVDD operating at 1.8 V. Key features include AC/DC lead-off detection, right leg drive, and shield driver capabilities. Unlike the standard ADAS1000, this model excludes respiration measurement and internal pace detection algorithms, focusing solely on ECG channel acquisition for diagnostic and monitoring applications.

Feature Summary

• Five dedicated ECG acquisition channels with selectable gain settings (×1.4 to ×4.2).
• Integrated Right Leg Drive (RLD) and Shield Driver for noise reduction.
• Programmable AC and DC lead-off detection thresholds.
• Supports scalable power/noise architecture with low power modes.

Applications

• Diagnostic ECG machines
• Bedside patient monitors
• Portable telemetry systems

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 56-lead LFCSP package variant when sourcing. Confirm that the absence of respiration and pace detection features aligns with system requirements, as these functions are reserved for the primary ADAS1000 model. Ensure compatibility with external microcontrollers supporting SPI interfaces for register configuration and data readout.

Selection Notes

Select the ADAS1000-1BCPZ when only ECG signal acquisition is required without integrated respiration or pace processing. This model serves as a cost-effective alternative to the full-featured ADAS1000 for systems where post-processing is handled externally. Pair with an ADAS1000-2 companion chip if more than five electrodes are needed for extended lead configurations.

Part Context

The ADAS1000-1 is part of the ADAS1000 family, designed alongside the ADAS1000 and ADAS1000-2. While the ADAS1000 includes respiration and pace detection, and the ADAS1000-2 is a secondary gang-mode device, the ADAS1000-1 provides a streamlined solution for pure ECG acquisition. It shares the same physical footprint and electrical interface as the other variants in the series.

Replacement Considerations

The ADAS1000BCPZ is a functional substitute but includes additional respiration and pace detection features not present in the ADAS1000-1. If these extra features are unnecessary, the ADAS1000-1 may offer a simpler configuration. No other direct pin-compatible replacements are documented in the provided datasheet.
