ADM803SAKSZ-REEL

Supervisors Overview

The ADM803SAKSZ-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a microprocessor supervisor. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 2.93 V with an accuracy of 1.5%. The device provides a reset delay time of 240 ms and supports both open drain and push-pull output types. It consumes 35 uA of operating current and includes an overvoltage threshold of 2.96 V. The component is housed in an SC-70-3 package, suitable for surface mount installation, and functions reliably across a temperature range from -40 C to +125 C.

Supervisors Feature Summary

• Provides reliable power supply monitoring with precise threshold detection capabilities
• Offers flexible output configuration supporting both open drain and push-pull drive modes
• Ensures system stability through defined reset delay timing under varying voltage conditions

Supervisors Applications

• Microprocessor system supervision
• Voltage monitoring in portable electronic devices
• Power management circuits requiring low quiescent current

Supervisors Procurement Notes

Verify the specific suffix REEL against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with SC-70-3 footprint requirements during PCB layout. Cross-reference the exact part number with manufacturer databases to confirm current production status and availability constraints before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a compact supervisory solution with configurable output drive is required. The dual output type capability allows integration with various logic families without additional level shifting. Consider the 35 uA quiescent current for battery-operated applications where power efficiency is critical alongside accurate voltage tracking.

Supervisors Part Context

This part belongs to the ADM803 series of voltage supervisors from Analog Devices. It is distinct from similar models like the ADM809 which may feature different output configurations or current consumption profiles. The SC-70-3 package offers a small form factor compared to larger industrial packages, making it suitable for space-constrained designs.
