ADM698AR-REEL

Supervisors Overview

The ADM698AR-REEL is a voltage supervisory integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 3V to 5.5V and features a push-pull output type. The device includes an integrated watchdog timer and provides a reset delay time of 280 ms. It has a threshold voltage specification ranging from 3V to 5.5V and an overvoltage threshold of 4.73 V. The component dissipates up to 375 mW of power and functions reliably across a temperature range of -40°C to +85°C. It is supplied in an SOIC-16 package.

Supervisors Feature Summary

• Integrates a watchdog timer for system monitoring
• Provides push-pull output configuration
• Operates with a wide supply voltage range

Supervisors Applications

• Microprocessor system supervision
• Power-on reset generation
• Watchdog timer implementation in embedded controllers

Supervisors Procurement Notes

Verify the exact suffix and packaging format, as the REEL designation indicates tape-and-reel packaging which differs from tube or cut-tape options. Confirm the specific threshold voltage variant required for the target application, as the series may offer multiple fixed or adjustable thresholds. Ensure the SOIC-16 package dimensions match the PCB footprint design. Check current availability status as distribution channels may list limited stock or end-of-life conditions for this specific reel quantity.

Supervisors Selection Notes

Select this component when a dedicated supervisor with an integrated watchdog is required alongside standard voltage monitoring. Compare the 280 ms reset delay against system startup timing requirements to ensure compatibility. Evaluate the 375 mW power dissipation limit against thermal constraints in the final enclosure. Consider the SOIC-16 package size relative to available board space compared to smaller alternatives like SOT-23 or DFN packages if space is critical.

Supervisors Part Context

The ADM698 belongs to the ADM69x family of CMOS supervisors designed for reliable operation in digital systems. This series typically combines power-on reset functionality with watchdog capabilities to prevent microprocessor lockups. The AR-REEL suffix specifically denotes the surface-mount SOIC-16 package configured for automated high-volume manufacturing processes using tape-and-reel dispensing systems.
