ADM803TAKS-REEL

Supervisors Overview

The ADM803TAKS-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a supply voltage range up to 5.5 V and features an open-drain output configuration. The device provides a reset delay time of 240 ms and maintains an accuracy of 1.5%. It functions reliably across an extended temperature range from -40°C to +125°C, with a typical operating supply current of 35 uA. The component is housed in a compact SC-70-3 surface-mount package.

Supervisors Feature Summary

• Provides reliable microprocessor supervision through precise voltage threshold monitoring
• Features low quiescent current consumption suitable for battery-powered applications
• Offers flexible output configuration via open-drain interface

Supervisors Applications

• Microprocessor system reset circuits
• Portable electronic device power management
• Industrial control board voltage supervision

Supervisors Procurement Notes

Verify the specific threshold voltage variant required, as the ADM803 series includes multiple options. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may be restricted. Ensure the SC-70-3 package matches your PCB footprint requirements before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when a simple, low-power supervisor is needed for single-rail monitoring. Consider the 240 ms reset delay and 1.5% accuracy against system timing requirements. Compare operating current and package size against alternatives if space or power constraints are critical. Verify that the open-drain output aligns with the target logic level and pull-up resistor configuration.

Supervisors Part Context

This part belongs to the ADM803 series of supervisory circuits from Analog Devices. These devices are engineered for cost-effective and space-constrained designs requiring basic power-on reset functionality. The series typically offers various threshold voltages to accommodate different standard logic levels and power rail specifications common in embedded systems.

Supervisors Replacement Considerations

Cross-reference with MAX803 variants for pin-compatible alternatives. Check ADM809 series for push-pull output options if open-drain is insufficient. Verify electrical parameters such as threshold voltage and reset delay match application needs before substitution.
