Procurement Notes

Verify the specific suffix 'LECQ+' against official Analog Devices documentation to confirm pinout, temperature range, and RoHS compliance status. Ensure the source document explicitly identifies this part number as a valid commercial offering rather than an obsolete or restricted variant before initiating procurement processes.

Selection Notes

Select this component when designing three-phase metering hardware requiring integrated signal conditioning and digital processing. The 100-LQFP package suits designs needing moderate pin counts with surface-mount assembly constraints. Evaluate the 128K flash capacity against application-specific firmware and data logging requirements.

Part Context

This component belongs to the MAX71334L family of polyphase electricity meter SoCs manufactured by Analog Devices/Maxim Integrated. These devices are engineered to replace discrete metering architectures by combining precision analog inputs with robust digital cores, simplifying PCB layout and reducing overall system component count.

Replacement Considerations

Publicly confirmed substitute part numbers include MAX71334LECQ+T.
