MAX9763EUI

Audio Amplifiers Overview

The MAX9763EUI+ is a Class-AB audio amplifier IC manufactured by Analog Devices Inc./Maxim Integrated. It features a single-channel mono output with stereo headphone capability, housed in a 28-TQFN (5x5) package. The device operates on a single supply voltage ranging from 4.5V to 5.5V. It delivers up to 3W of power into a 3-ohm load or 200mW into two 16-ohm loads. Key electrical specifications include an operating temperature range of -40°C to +85°C and compliance with RoHS3 standards.

Audio Amplifiers Feature Summary

• Integrates pop-and-click suppression circuitry to minimize audible transients during power-up and power-down sequences.
• Includes input multiplexing functionality for flexible signal routing and source selection.
• Provides integrated mute and shutdown modes to reduce power consumption when the system is inactive.
• Features built-in thermal protection to safeguard the device against overheating under fault conditions.

Audio Amplifiers Applications

• Portable multimedia devices requiring high-efficiency audio amplification
• Stereo headphone amplifier circuits in consumer electronics
