Product details

Switch and sounder controller on I²C

The Maxim Integrated MAX7349AEG is a switch and sounder controller designed to manage multiple switch inputs and drive a sounder (buzzer/transducer) under I²C bus control. It targets applications such as sound cards, players, and recorders where a clean, programmable switch-matrix scan and audible feedback are needed without loading the host MCU.

Lifecycle and compliance

Marked as Active in production. Note that the part is listed as RoHS non-compliant — verify local regulatory requirements before specifying.

Frequently asked questions

What is MAX7349AEG's I²C interface used for?

The I²C bus handles all register configuration — key-debounce timing, sounder frequency/duration, and interrupt masking — plus readback of pressed keys. This offloads the host from continuous scanning.

Does MAX7349AEG have a RoHS compliant variant?

This specific order code (MAX7349AEG) is listed as RoHS non-compliant. Check the manufacturer's ordering guide for a lead-free suffix variant if RoHS compliance is required.

What applications is MAX7349AEG suitable for?

The listed applications include sound cards, players, and recorders — any system that needs a dedicated switch matrix scanner with integrated sounder drive to reduce host MCU overhead.
