ADM1294-1AARUZ

Overview

The ADM1294-1AARUZ is a single-phase energy metering IC designed for low-side supply monitoring. It features an integrated shunt regulator, enabling operation in wide voltage ranges. The device supports a supply voltage range of 2.95 V to 13 V and draws a typical supply current of 3.6 mA. It operates within a temperature range of -40°C to 105°C and is housed in a 14-TSSOP surface-mount package.

Feature Summary

• Integrated shunt regulator facilitates power and monitoring in wide voltage ranges
• Designed specifically for low-side supply monitoring applications
• Single-phase metering capability for system health assessment

Applications

• -48V power monitoring systems
• Advanced system health monitoring in power supplies
• Low-side supply monitoring circuits

Procurement Notes

Verify the exact suffix (e.g., -RL7) against your bill of materials, as reel packaging variants exist. Confirm availability status directly with authorized distributors, as stock levels fluctuate. Ensure the 14-TSSOP package matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when low-side monitoring with an integrated shunt regulator is required. It is suitable for single-phase applications operating between 2.95 V and 13 V. Consider the industrial temperature range (-40°C to 105°C) for harsh environments. Verify that the open-drain or specific output interface meets your microcontroller input requirements.

Part Context

This part belongs to Analog Devices' digital power monitor family, focusing on system health monitoring. It complements other ADM12xx series devices by offering specialized low-side monitoring capabilities. The integration of the shunt regulator distinguishes it from standard voltage supervisors, allowing direct connection to shunt resistors for current sensing.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult Analog Devices official resources for cross-reference data or verify compatibility with alternative low-side monitors based on specific electrical parameters.
