ADM803SAKSZ-REEL7

Supervisors Overview

The ADM803SAKSZ-REEL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 1 V to 5.5 V and features a fixed reset threshold voltage of 2.63 V with an accuracy of 1.5%. The device provides a push-pull output and includes a reset delay time of 240 ms. It consumes a typical operating supply current of 35 uA. The component supports a maximum power supply voltage of 5.5 V and functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a compact SC-70-3 surface-mount package.

Supervisors Feature Summary

• Provides reliable system reset for microprocessors and memory devices
• Features a fixed 2.63 V threshold for precise voltage monitoring
• Includes a built-in 240 ms reset pulse width timer
• Operates with low quiescent current for energy efficiency

Supervisors Applications

• Microprocessor power supply supervision
• Battery-powered portable equipment
• Memory protection circuits
• Embedded control systems

Supervisors Procurement Notes

Verify the specific suffix 'S' indicates the 2.63 V threshold variant when sourcing replacements. Confirm the 'REEL7' designation matches the required tape and reel packaging quantity for automated assembly processes. Ensure the SC-70-3 footprint aligns with existing PCB layout constraints before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 2.63 V reset threshold is required for 3.3 V or 5 V logic systems. The push-pull output allows direct driving of digital inputs without external pull-ups. Consider the 35 uA standby current for battery life optimization. Verify that the 240 ms delay meets the minimum power-up time requirements of the target application.

Supervisors Part Context

This part belongs to the ADM803 series of voltage supervisors from Analog Devices. It complements other variants like the ADM809 and ADM810, which offer different threshold voltages. The series is designed for cost-sensitive applications requiring robust power management. The SC-70-3 package offers space savings compared to larger SOIC options while maintaining similar electrical performance characteristics.
