ADAS1000BSTZ-RL

Overview

The ADAS1000BSTZ-RL is a low-power, five-electrode electrocardiogram (ECG) analog front end from Analog Devices Inc., housed in a 64-lead LQFP package. It features five acquisition channels and one driven lead, supporting up to 10+ electrode measurements when paralleled with secondary devices like the ADAS1000-2. The device digitizes biopotential signals with a resolution of 19 bits at 2 kHz data rates and 18 bits at 16 kHz. It operates on an AVDD supply ranging from 3.15 V to 5.5 V and includes internal AC/DC lead-off detection, pace detection algorithms, and thoracic impedance measurement capabilities.

Feature Summary

• Five ECG acquisition channels with integrated right leg drive and shield driver
• Supports AAMI EC11:1991/(R)2007 and IEC60601-1 ed. 3.0 b:2005 standards
• Scalable noise vs. power control with selectable high-performance or low-power modes
• Integrated calibration DAC and cyclic redundancy check (CRC) for testing

Applications

• Bedside patient monitoring systems
• Portable telemetry and Holter monitors
• Automated external defibrillators (AED) and cardiac defibrillators
• Ambulatory monitors and stress testing equipment

Procurement Notes

Verify the ordering suffix -RL indicates reel packaging. Confirm the BSTZ suffix corresponds to the 64-lead LQFP package variant. Ensure compatibility with the required IOVDD range of 1.65 V to 3.6 V for digital interfaces. Check for moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this model over the ADAS1000BCPZ-RL if a 64-lead LQFP package is preferred over the 56-lead LFCSP. Choose the ADAS1000BSTZ-RL specifically for applications requiring respiration and pace detection features, which are absent in the ADAS1000-1 variant. Consider pairing with an ADAS1000-2 secondary device to expand channel count beyond five electrodes.

Part Context

This component belongs to the ADAS1000 series, which also includes the ADAS1000-1 (no respiration/pace) and ADAS1000-2 (secondary companion). The BSTZ suffix denotes the specific 64-lead LQFP physical package, distinguishing it from the BCPZ suffix used for the 56-lead LFCSP package within the same functional family.

Replacement Considerations

The ADAS1000BCPZ-RL is a direct functional substitute differing only by package type (56-lead LFCSP vs. 64-lead LQFP). Other ADAS1000 variants may require firmware changes due to missing features like respiration or pace detection.
