ADM708AR-REEL

Supervisors Overview

The ADM708AR-REEL is a microprocessor supervisory circuit designed for monitoring 3 V or 3.3 V power supplies. It features a precision voltage monitor with a threshold of 4.40 V and provides both active high and active low push-pull reset outputs. The device ensures valid RESET signals down to VCC = 1 V, with a fixed 200 ms reset pulse width. It includes a debounced manual reset input and operates within a temperature range of -40°C to +85°C. Quiescent current is specified at 190 μA, and it is housed in an 8-SOIC package.

Supervisors Feature Summary

• Provides dual active high and active low reset outputs for flexible logic interfacing
• Guarantees valid reset functionality even when supply voltage drops to 1 V
• Includes a debounced manual reset input compatible with TTL/CMOS standards

Supervisors Applications

• Microprocessor systems requiring critical supply monitoring
• Portable instruments and battery-powered devices
• Controllers and intelligent instrumentation

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout compatibility and electrical characteristics. Ensure the reel packaging matches production requirements. Cross-reference the exact part number with current datasheets to validate manufacturing status and environmental compliance before integration into designs.

Supervisors Selection Notes

Select this component for applications requiring simultaneous high and low active reset signals without watchdog timer functionality. It serves as a direct upgrade for legacy MAX708 designs. Verify that the 4.40 V threshold aligns with the target system's voltage rails and that the 190 μA quiescent current meets power budget constraints.

Supervisors Part Context

This device belongs to the ADM705/ADM706/ADM707/ADM708 family of microprocessor supervisory circuits manufactured by Analog Devices. These components are engineered to replace older Maxim Integrated parts, offering improved performance while maintaining functional compatibility. The series is widely used in industrial and consumer electronics for reliable power management.

Supervisors Replacement Considerations

MAX708RESA+ and MAX708REUA+ are confirmed functional substitutes within the same supervisory circuit family.
