Audio Amplifiers datasheet and documents for MAX9751ETI+T

MAX9751ETI+T

Audio Amplifiers Overview

The MAX9751ETI+T is a stereo audio power amplifier and DirectDrive headphone amplifier from Analog Devices. It integrates a 2.6W Class AB BTL speaker amplifier and a 110mW DirectDrive headphone driver in a single device. The unit operates on a 4.5V to 5.5V single supply, featuring a 2:1 stereo input multiplexer for source selection. Key electrical parameters include a 90dB PSRR, 0.01% THD+N at 1kHz, and a maximum gain of 10.5dB. It utilizes a 28-pin Thin QFN (5mm x 5mm) package and functions within an extended temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

Integrates a 2:1 stereo input multiplexer for selecting between multiple audio sources
Employs DirectDrive architecture to eliminate the need for bulky DC-blocking capacitors
Features industry-leading click-and-pop suppression during power and shutdown cycles
Includes automatic headphone detection via the HPS input pin

Audio Amplifiers Procurement Notes

Verify the component authenticity by checking the manufacturer's marking against official datasheet specifications. Confirm the package type matches the 28-pin Thin QFN format. Ensure the ordering suffix corresponds to the specific variant required for your design. Cross-reference the part number with authorized distributors to confirm availability status.

Audio Amplifiers Selection Notes

Select this model when a system requires integrated speaker and headphone amplification without external coupling capacitors. The built-in 2:1 multiplexer simplifies designs needing dual audio source inputs. It is suitable for applications requiring high power-supply rejection and low distortion within a compact footprint.

Audio Amplifiers Part Context

This component belongs to the MAX975x family, which combines stereo audio power amplifiers with DirectDrive headphone drivers. The series is designed to provide high-fidelity audio output while minimizing board space through the elimination of large passive components typically required for single-supply operation.
