ADM708ARMZ-REEL

Supervisors Overview

The ADM708ARMZ-REEL is a microprocessor supervisory circuit from Analog Devices, designed for monitoring 5 V power supplies and batteries. It features a precision voltage monitor with a threshold of 4.40 V and provides an active high reset output. The device guarantees RESET validity down to VCC = 1 V and includes a debounced manual reset input. It operates within a supply voltage range of 1 V to 5.5 V, consumes 190 μA quiescent current, and supports a reset pulse width of 200 ms. The component is housed in an 8-SOIC package.

Supervisors Feature Summary

• Provides active high reset output with guaranteed validity at low supply voltages
• Includes debounced manual reset input compatible with TTL/CMOS logic
• Features precision voltage monitoring for power-fail or low battery warnings

Supervisors Applications

• Microprocessor systems
• Computers

• Intelligent instruments
• Critical microprocessor supply monitoring

Supervisors Procurement Notes

Verify the specific suffix against official documentation to confirm reel packaging and tape specifications. Confirm that the active high configuration matches system requirements. Check for obsolescence status as distribution availability may vary. Ensure environmental compliance data aligns with project constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when an active high reset signal is required for the target microprocessor architecture. The 4.40 V threshold suits standard 5 V supply monitoring applications. Consider the 190 μA quiescent current for power-sensitive designs. Verify compatibility with the 8-SOIC surface-mount footprint during PCB layout planning.

Supervisors Part Context

This part belongs to the ADM705/ADM706/ADM707/ADM708 series of microprocessor supervisory circuits. These devices are engineered to monitor power supplies and ensure reliable system resets. The series offers various output polarities and thresholds to accommodate different processor requirements.

Supervisors Replacement Considerations

The ADM708ARZ is a tube-packaged equivalent within the same family. Verify pinout and electrical characteristics match before substitution.
