ADM1294-1BARUZ-RL7

Overview

The ADM1294-1BARUZ-RL7 is a high-accuracy integrated digital power monitor featuring a PMBus interface. It provides precise monitoring of current, voltage, and power using an on-chip analog-to-digital converter. The device supports low-side supply monitoring with an integrated shunt regulator for wide voltage range operation. It is housed in a 14-TSSOP package and operates within a specified temperature range suitable for industrial applications.

Feature Summary

• Integrated digital power monitoring for current, voltage, and power calculations
• PMBus interface for digital communication and configuration
• On-chip analog-to-digital conversion for high accuracy measurements
• Low-side supply monitoring capability with integrated shunt regulator

Applications

• Energy metering systems
• Industrial power supply monitoring
• Telecommunications power management
• Server and storage power rails supervision

Procurement Notes

Verify the exact suffix -RL7 indicates reel packaging when sourcing. Confirm the BARUZ variant specifications against the official Analog Devices datasheet to ensure compatibility with your system requirements. Check for end-of-life notifications or discontinuation status as availability may be limited.

Selection Notes

Select this component when precise digital power monitoring via PMBus is required. Ensure the low-side monitoring architecture fits your circuit design. Verify that the 14-TSSOP package size meets your PCB layout constraints. Compare performance metrics against similar ADM1293 or ADM1295 models if different channel counts are needed.

Part Context

This part belongs to the ADM129x family of digital power monitors from Analog Devices. These devices are designed for high-accuracy energy measurement and power management in demanding environments. The family shares common PMBus protocols but varies in channel count and specific feature sets.

Replacement Considerations

The ADM1293-1BARUZ series offers similar functionality with potential differences in channel configuration. Verify pinout compatibility and software register mapping before substitution. Consult the official cross-reference guide for approved alternatives.
