ADM706SANZ

Supervisors Overview

The ADM706SANZ is a microprocessor supervisory circuit designed for monitoring 3 V or 3.3 V power supplies in through-hole applications. It features a precision voltage monitor with a typical threshold of 2.93 V and supports a supply voltage range up to 5.5 V. The device provides an active low, push-pull reset output with a guaranteed reset valid at VCC = 1 V. Key functional parameters include a manual reset input, an independent watchdog timer with a 1.6-second timeout, and a reset pulse width of approximately 280 ms. Operating current is specified at 250 uA, and the component functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates a precision voltage monitor with a debounced manual reset input for reliable system control
• Includes an independent watchdog timer with a fixed 1.6-second timeout interval
• Provides an active low, push-pull reset output ensuring valid reset signals down to 1 V supply

Supervisors Applications

• Microprocessor systems requiring critical power supervision
• Battery-operated portable instruments
• Controllers and intelligent instruments

Supervisors Procurement Notes

Verify component authenticity due to discontinued status. Confirm package integrity as DIP-8 units may have aged. Check datasheet revisions for parameter consistency. Ensure compatibility with existing PCB footprints. Validate supplier provenance for long-term reliability.

Supervisors Selection Notes

Select this part for through-hole designs needing a 2.93 V threshold. Compare quiescent current against low-power alternatives if battery life is critical. Verify that the 1.6-second watchdog timeout meets system timing requirements. Ensure the active low output polarity matches the target processor interface.

Supervisors Part Context

This component belongs to the ADM706 series of voltage monitoring circuits from Analog Devices. It serves as a successor to legacy MAX706 devices, offering improved performance in microprocessor supervision. The 'Z' suffix indicates RoHS compliance, while 'SAN' denotes the specific threshold voltage and PDIP-8 package configuration within the product family.
