ADAS1000-2BCPZ-RL

Overview

The ADAS1000-2BCPZ-RL is a biopotential analog front-end (AFE) designed for ECG applications, featuring five acquisition channels and one driven lead. It operates as a secondary companion device in gang mode with primary ADAS1000 units to expand channel counts beyond ten electrodes. The component utilizes a 56-lead LFCSP package and supports SPI/QSPI/DSP-compatible serial interfaces. Key electrical parameters include a 3.15 V to 5.5 V supply range, 19-bit resolution at 2 kHz data rates, and an input-referred noise of 11 μV p-p in electrode mode. Power consumption reaches 21 mW with all electrodes active.

Feature Summary

• Secondary AFE for multi-chip ECG systems supporting up to 10+ electrodes
• Five ECG acquisition channels with differential amplifier inputs
• Scalable noise vs. power control architecture with low-power modes
• Integrated calibration DAC and CRC redundancy testing

Applications

• Multi-channel ECG monitoring systems
• Portable telemetry and Holter monitors
• Bedside patient monitoring stations
• Cardiac defibrillators and AEDs

Procurement Notes

Verify the BCPZ suffix confirms the 56-lead LFCSP package variant. Confirm the -RL designation indicates reel packaging. Ensure the specific revision matches system requirements, as pinouts and features may vary between revisions. Cross-reference with primary ADAS1000 devices for gang mode compatibility.

Selection Notes

Select this part when expanding channel count beyond a single chip's capacity. It lacks standalone respiration and pace detection features, requiring a primary ADAS1000 or ADAS1000-1 for those functions. Verify IOVDD compatibility with the host microcontroller logic levels before integration.

Part Context

Part of the ADAS1000 family, specifically engineered as a slave device. Unlike the full-featured ADAS1000, it disables right leg drive, respiration, and pace detection circuits to optimize for parallel operation. It shares the same physical footprint and interface protocols as the primary variants.

Replacement Considerations

Direct functional substitutes within the same family include ADAS1000BSTZ-RL (LQFP package). Standalone replacements are not recommended due to the specific gang-mode configuration; alternative designs require re-evaluating the entire signal chain architecture.
