MAX9760EUI+T

Audio Amplifiers Overview

The MAX9760EUI+T is a stereo audio power amplifier from the MAX9760–MAX9763 family, manufactured by Analog Devices Inc./Maxim Integrated. It integrates a 3W bridge-tied load (BTL) speaker amplifier and a 200mW single-ended headphone amplifier within a single device. Operating from a single 4.5V to 5.5V supply, it features an industry-leading 100dB PSRR at 1kHz and ultra-low THD+N of 0.002%. The component includes a 2:1 input multiplexer, headphone sensing logic, click-and-pop suppression, and thermal overload protection. It is housed in a 28-pin TSSOP-EP package and operates over an extended temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• Integrates a 3W BTL stereo speaker amplifier and a 200mW stereo headphone amplifier with automatic mode switching via headphone sense input.
• Features industry-leading 100dB power-supply rejection ratio (PSRR) for operation on noisy digital supplies without linear regulators.
• Includes a 2:1 input multiplexer allowing selection between two audio sources or external equalization networks.
• Provides comprehensive click-and-pop suppression during power-up and shutdown cycles.

Audio Amplifiers Applications

• Notebooks
• Portable DVD Players
• Tablet PCs
• PC Audio Peripherals
• Camcorders

Audio Amplifiers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm the 'EUI' designation corresponds to the 28-pin TSSOP-EP package variant rather than the QFN version. Ensure the '+T' suffix aligns with lead-free RoHS compliance requirements. Cross-reference the manufacturer part number against current availability status as distribution channels may vary.

Audio Amplifiers Selection Notes

Select this component for designs requiring integrated speaker and headphone amplification in a compact form factor. The I2C-compatible interface allows for flexible gain and input source configuration. Consider the low quiescent current and shutdown mode for battery-powered applications. Verify that the required output power into the specific load impedance falls within the specified operational limits.

Audio Amplifiers Part Context

This device belongs to the MAX9760–MAX9763 family of stereo and mono audio power amplifiers. The family combines high-efficiency amplification with advanced control features such as input multiplexing and headphone detection. These devices are designed to replace discrete amplifier solutions, reducing board space and component count in portable multimedia electronics.

Audio Amplifiers Replacement Considerations

Public confirmed substitute part numbers: MAX9760ETI+, MAX9761EUI+, MAX9762EUI+, MAX9763EUI+. Verify pin compatibility and control interface differences (I2C vs. parallel) before substitution.
