ADM708TANZ

Supervisors Overview

The ADM708TANZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supplies and batteries. It features a precision voltage monitor with a typical threshold of 4.4 V, suitable for 5 V systems. The device provides an active high reset output with a fixed reset pulse width of 200 ms. It includes a debounced manual reset input and operates within a supply voltage range of 1 V to 5.5 V. The component draws a quiescent current of 190 μA and functions across an industrial temperature range of -40°C to +85°C. It is housed in an 8-lead SOIC package.

Supervisors Feature Summary

• Precision supply voltage monitoring with guaranteed valid reset down to 1 V
• Active high reset output configuration for direct logic interfacing
• Debounced manual reset input compatible with TTL/CMOS standards
• Low quiescent current consumption for battery-powered applications

Supervisors Applications

• Microprocessor system power supervision
• Critical microprocessor supply monitoring
• Controllers and intelligent instruments
• Computers requiring low-cost supervisory solutions

Supervisors Procurement Notes

Verify the specific suffix 'TANZ' against official Analog Devices documentation to confirm package type and temperature grade, as standard listings often use 'AR' or 'AN'. Confirm end-of-life status and last-time-buy dates via manufacturer notices. Ensure RoHS compliance matches project requirements. Cross-reference pinouts with the official datasheet to avoid compatibility issues with legacy MAX708 designs.

Supervisors Selection Notes

Select this component when an active high reset signal is required for 5 V logic systems. It serves as a direct upgrade for MAX708 devices with improved accuracy. Consider the 200 ms reset delay for system startup timing. Verify that the 190 μA quiescent current meets power budget constraints. Ensure the SOIC package fits the PCB layout constraints compared to DIP alternatives.

Supervisors Part Context

The ADM708 belongs to the ADM705-ADM708 family of low-cost microprocessor supervisory circuits from Analog Devices. This series is engineered to monitor 5 V power supplies and batteries while also tracking microprocessor activity. The ADM708 variant specifically distinguishes itself by providing an active high reset output, unlike the active low variants in the same family.

Supervisors Replacement Considerations

MAX708CPA+ and MAX708EPA+ are listed as similar replacements. Verify pin compatibility and reset polarity differences between Maxim Integrated and Analog Devices versions before substitution.
