ADAQ4381-4BBCZ

Overview

The ADAQ4381-4BBCZ is a four-channel data acquisition module from Analog Devices, integrating a 14-bit, 4 MSPS ADC with signal conditioning and power management in a single system-in-package. It supports both full-differential and single-ended inputs, featuring an integrated high-precision reference with 3 ppm/°C drift and internal buffers for common-mode voltage generation. The device utilizes a high-speed serial interface and includes on-chip oversampling to boost resolution by two bits.

Feature Summary

• Integrated 14-bit, 4 MSPS ADC with ADC drivers and power management
• Supports full-differential and single-ended input configurations
• On-chip oversampling capability providing 2-bit resolution enhancement
• Integrated precision voltage reference with 3 ppm/°C typical drift

Applications

• Laboratory-grade battery test systems
• Motor control current detection
• Motor control position feedback
• Sonar systems
• Power quality monitoring

Procurement Notes

Verify the specific suffix BBCZ against the official datasheet to confirm package type and temperature range. Confirm availability status as supply may be limited or restricted depending on the region. Ensure compatibility with existing board layouts and power requirements before procurement.

Selection Notes

Select this module when space constraints require integration of ADC, drivers, and references. It is suitable for applications needing 14-bit resolution at up to 4 MSPS per channel. Consider the 5 V single-supply operation and the need for differential or single-ended inputs when designing the signal chain.

Part Context

This component belongs to the ADAQ μModule family, which consolidates multiple discrete components into a single system-level package. It is designed to reduce terminal system component count and simplify the development of precision measurement systems compared to discrete solutions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical specifications carefully if considering alternative modules from other manufacturers.
