Audio Amplifiers datasheet and documents for MAX9761EUI+T

MAX9761EUI+T

Audio Amplifiers Overview

The MAX9761EUI+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 28-pin TSSOP-EP package. The device operates on a single 4.5V to 5.5V supply and features a 100dB power-supply rejection ratio (PSRR). Key electrical parameters include a quiescent current of 13mA in BTL mode, a shutdown current of 10µA, and an output offset voltage of ±4mV. It delivers up to 3W into a 3Ω load with less than 1% THD+N.

Audio Amplifiers Feature Summary

Integrates a 3W BTL stereo speaker amplifier and a 200mW stereo headphone amplifier
Features industry-leading 100dB PSRR for operation from noisy supplies
Includes automatic headphone sensing to switch between speaker and headphone modes
Provides click-and-pop suppression during power cycles

Audio Amplifiers Applications

Notebooks
Portable DVD Players
Tablet PCs
PC Audio Peripherals
Camcorders

Audio Amplifiers Procurement Notes

Verify the specific suffix EUI corresponds to the 28-pin TSSOP-EP package and -40°C to +85°C temperature range as documented in the official datasheet. Confirm RoHS compliance status through manufacturer documentation. Ensure the ordering code matches the exact functional variant required, as the family includes I2C-controlled and parallel-interface versions.

Audio Amplifiers Selection Notes

Select this component when a compact solution is needed for both speaker and headphone driving from a single 5V rail. The MAX9761 variant utilizes a simple parallel control interface rather than an I2C bus. Consider the thermal performance of the TSSOP-EP package for high-power applications and verify that the external gain-setting resistors align with the desired output levels for the target loads.

Audio Amplifiers Part Context

This part belongs to the MAX9760–MAX9763 family of stereo audio amplifiers. The family differentiates models based on their control interface: MAX9760/MAX9762 use an I2C-compatible serial interface, while MAX9761/MAX9763 use parallel logic inputs. The MAX9761 specifically offers stereo BTL and stereo headphone outputs controlled via dedicated pins.
