ADM697AN

Supervisors Overview

The ADM697AN is a single-channel CMOS supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage supply and provides a reset signal when the monitored voltage drops below a specific threshold. The device operates within a supply voltage range of 3 V to 5.5 V and features an active-low push-pull output. It includes a fixed reset delay time of 70 ms to ensure stable power-up sequencing. The component is housed in a 16-pin CDIP package and supports operation across an industrial temperature range from -55 °C to +125 °C.

Supervisors Feature Summary

• Provides reliable system reset generation for microprocessors and memory circuits during power supply disturbances
• Features a fixed internal reset delay timer to prevent false triggering during power ramp-up
• Delivers a robust active-low push-pull output capable of driving standard logic inputs directly

Supervisors Applications

• Microprocessor (MPU) supervisor systems requiring precise power monitoring
• CMOS memory circuits needing automatic reset upon voltage loss
• Industrial control units operating in extended temperature environments

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as variations may indicate different thermal grades or packaging options. Confirm RoHS compliance status and lead times through authorized distributors, as availability for this specific part number may be limited or subject to change based on production cycles.

Supervisors Selection Notes

Select this component when a fixed threshold supervisor with a 70 ms delay is required for 5 V CMOS systems. Ensure the application demands a single-channel monitor with an active-low output. Verify that the 16-pin ceramic DIP package fits the mechanical constraints and that the wide temperature range meets environmental requirements.

Supervisors Part Context

The ADM697 belongs to the ADM696/ADM697 family of supervisory circuits designed for critical power management applications. These devices are engineered to provide deterministic reset behavior for digital systems. The AN suffix typically denotes the standard commercial or industrial grade variant in the ceramic DIP package, distinguishing it from other thermal or plastic package options within the same functional family.

Supervisors Replacement Considerations

Check for direct equivalents such as the MAX697 series from Maxim Integrated, which shares similar pinouts and functionality. Verify parameter compatibility regarding threshold voltages and reset delays before substitution.
