ADM708TAR-REEL

Supervisors Overview

The ADM708TAR-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply integrity in electronic systems. It operates within a supply voltage range of 1 V to 5.5 V and features a typical reset threshold voltage of 4.4 V. The device provides a manual reset input and supports active high, active low, or push-pull output configurations. It includes power-fail detection capabilities and maintains a maximum supply current of 350 uA. The component is housed in an 8-SOIC package with an industrial operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable voltage supervision with configurable active high, active low, or push-pull outputs for flexible system integration.
• Includes a manual reset input allowing external control over the reset state independent of voltage monitoring.
• Features integrated power-fail detection to identify abnormal supply conditions before they cause system errors.

Supervisors Applications

• Microprocessor system power monitoring
• Controller board voltage supervision
• Smart instrument power management

Supervisors Procurement Notes

Verify the specific suffix 'REEL' indicates tape-and-reel packaging rather than tube packaging when sourcing. Confirm the exact threshold voltage variant required, as the ADM708 series offers multiple options. Check current lifecycle status, as some variants may be discontinued or have limited availability. Ensure compatibility with existing PCB footprint specifications for the 8-SOIC package.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with manual reset capability is required. Compare threshold voltages against the target supply rail to ensure accurate triggering. Consider the output driver type (push-pull vs open collector) based on downstream logic requirements. Verify that the 350 uA maximum supply current meets the system's power budget constraints.

Supervisors Part Context

This part belongs to the ADM705/ADM706/ADM707/ADM708 family of microprocessor supervisory circuits from Analog Devices. These devices are engineered to provide simple reset generation and power-fail signaling for digital systems. The ADM708 specifically targets applications requiring a 4.4 V threshold, distinguishing it from lower-voltage variants in the same series.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers include MAX708TARZ and MAX708TEPA+. Verify pinout compatibility and electrical parameter alignment before substitution.
