Procurement Notes

Verify the specific suffix V+ against official Analog Devices documentation to confirm tape-and-reel packaging status. Confirm that the part number corresponds to the automotive-grade or industrial-grade variant required for your application environment. Check current lifecycle status as distribution availability may be restricted due to end-of-life notifications.

Selection Notes

Select this component when a high channel count is required within a limited footprint. Ensure the system supply voltage remains within the 6V to 72V operational range. Verify that the serial interface timing requirements align with the host microcontroller capabilities. Consider thermal dissipation characteristics if operating at maximum channel utilization.

Part Context

This component belongs to the MAX11080 family of high-voltage battery monitors. It shares architectural similarities with the MAX11081, which offers automotive qualification. The GUU/V+ designation indicates a specific package and reel configuration within the broader product line managed by Analog Devices.

Replacement Considerations

The MAX11081GUU/V+ serves as a qualified alternative for automotive applications. Verify pin compatibility and software register mapping before substitution. Ensure the replacement meets the specific temperature grade and reliability standards of the original design.
