Audio Amplifiers datasheet and documents for MAX9728BEUD+T

MAX9728BEUD+T

Audio Amplifiers Overview

The MAX9728BEUD+T is a stereo Class AB headphone amplifier utilizing DirectDrive architecture for single-supply operation. It delivers up to 60mW per channel into a 32Ω load with 0.02% THD+N. Operating from a 4.5V to 5.5V supply, it features an internally fixed gain of -1.5V/V and low quiescent current of 3.5mA. The device includes integrated click-and-pop suppression, short-circuit protection, thermal overload protection, and a low-power shutdown mode consuming less than 0.1µA.

Audio Amplifiers Feature Summary

DirectDrive architecture eliminates bulky DC-blocking capacitors by generating an internal negative supply via a charge pump.
Integrated click-and-pop suppression circuitry prevents audible transients during startup and shutdown transitions.
Low-power shutdown mode reduces supply current consumption to less than 0.1µA when disabled.
Comprehensive protection mechanisms include thermal-overload limiting and continuous short-circuit protection.

Audio Amplifiers Applications

Notebook PCs
LCD/PDP Displays
DVD Players

Audio Amplifiers Procurement Notes

Verify the specific suffix 'U' indicates the 14-pin TSSOP package configuration rather than the alternative QFN option. Confirm that the 'B' designation corresponds to the fixed -1.5V/V gain setting required for the design. Ensure compatibility with the specified 4.5V to 5.5V single-supply voltage range and check for lead-free/RoHS compliance status on the ordering documentation.

Audio Amplifiers Selection Notes

Select this component when board space constraints prohibit the use of large output coupling capacitors typical in conventional amplifiers. The fixed -1.5V/V gain simplifies external resistor networks compared to adjustable variants. Consider the 14-pin TSSOP package if through-hole or larger pitch surface-mount assembly is preferred over the smaller QFN footprint.

Audio Amplifiers Part Context

This part belongs to the MAX9728 family of DirectDrive stereo headphone amplifiers designed for portable electronics. It shares core functionality with the MAX9728A but differs in gain configuration and packaging options. The family targets applications requiring high audio fidelity and minimal external component counts within tight spatial limitations.
