ADAS1000-2BSTZ

Overview

The ADAS1000-2BSTZ is a five-channel ECG analog front-end (AFE) designed as a companion device for the ADAS1000 or ADAS1000-1. It provides five acquisition channels and supports parallel IC configurations for up to 10+ electrode measurements. The device features AC and DC lead-off detection, selectable reference leads, and scalable noise versus power control with power-down modes. It operates from a 3.15 V to 5.5 V supply, consumes 21 mW with all electrodes active, and offers low or high-speed data output rates via a serial interface compatible with SPI/QSPI/DSP standards.

Feature Summary

• Five ECG acquisition channels configured for gang mode operation with primary devices
• Supports up to 10+ electrode measurements through parallel IC configuration
• AC and DC lead-off detection capabilities
• Scalable noise vs. power control architecture with selectable power-down modes

Applications

• ECG monitor and diagnostic systems
• Bedside patient monitoring and portable telemetry
• Holter monitors and ambulatory cardiac monitors
• Automated external defibrillators (AED) and cardiac defibrillators
• Pacemaker programmers and patient transport systems

Procurement Notes

Verify that the ADAS1000-2BSTZ is paired with a primary ADAS1000 or ADAS1000-1 device, as it lacks standalone functionality. Confirm package type matches design requirements: LQFP-64 for BSTZ suffix. Ensure system design accounts for secondary serial interface timing and calibration DAC input connections specified in the datasheet.

Selection Notes

Select the ADAS1000-2BSTZ when expanding channel count beyond five electrodes using Analog Devices primary AFEs. Choose this model over the ADAS1000 if respiration and pace detection are handled by the primary device. Verify IOVDD compatibility (1.65 V to 3.6 V) with the host microcontroller. Consider thermal resistance of 42.5°C/W for the LQFP package in heat dissipation calculations.

Part Context

The ADAS1000-2 is part of the ADAS1000 family, which includes the full-featured ADAS1000, the ECG-only ADAS1000-1, and three-electrode variants ADAS1000-3 and ADAS1000-4. While the ADAS1000 integrates respiration and pace detection, the ADAS1000-2 is a subset device optimized for gang mode expansion, providing only ECG channels without right leg drive or shield driver functions.
