MAX9765ETJ

Audio Amplifiers Overview

The MAX9765ETJ is a stereo audio amplifier manufactured by Analog Devices Inc./Maxim Integrated, housed in a 32-TQFN package. It delivers 750mW of output power and integrates a dedicated headphone amplifier, microphone preamplifier, and input multiplexer. The device operates within a supply voltage range of 2.7V to 5.5V and supports a wide operating temperature range from -40°C to +85°C.

Audio Amplifiers Feature Summary

• Integrates a high-performance microphone preamplifier for direct microphone connection
• Includes an input multiplexer to select between multiple audio sources
• Features built-in pop-and-click suppression circuitry to minimize audible transients

Audio Amplifiers Applications

• Portable multimedia devices requiring integrated audio front-end
• Mobile phones with combined speaker and headphone outputs
• Digital media players utilizing internal microphone inputs

Audio Amplifiers Procurement Notes

Verify the specific suffix ETJ against the manufacturer's current part numbering system to ensure correct pinout and thermal pad configuration. Confirm RoHS compliance status and check for any recent lifecycle notices or obsolescence warnings directly from Analog Devices documentation before finalizing procurement plans.

Audio Amplifiers Selection Notes

Select this component when a design requires a single-chip solution combining stereo speaker amplification, headphone driving capability, and microphone preamplification. The integrated input mux simplifies board layout by reducing external switching components compared to discrete solutions.

Audio Amplifiers Part Context

This part belongs to the MAX976x series of low-power audio amplifiers designed for portable electronics. It shares functional similarities with other Maxim audio ICs but is distinct due to its specific combination of 750mW stereo output and integrated analog front-end peripherals for voice and music applications.
