Audio Amplifiers datasheet and documents for MAX9728BEUD+

MAX9728BEUD+

Audio Amplifiers Overview

The MAX9728BEUD+ is a stereo 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. The device operates from a 4.5V to 5.5V supply, consuming 3.5mA quiescent current and less than 0.1µA in shutdown mode. It features an internally preset gain of -1.5V/V, integrated click-and-pop suppression, and short-circuit/thermal protection. Available in a 14-pin TSSOP package.

Audio Amplifiers Feature Summary

DirectDrive architecture eliminates bulky DC-blocking capacitors by using a charge pump to create bipolar supplies from a single rail.
Integrated low-power shutdown mode reduces current consumption to extend battery life in portable applications.
Comprehensive click-and-pop suppression circuitry prevents audible transients during startup and shutdown transitions.

Audio Amplifiers Applications

Notebook PCs
DVD Players
LCD/PDP Displays

Audio Amplifiers Procurement Notes

Verify the specific suffix 'UD+' corresponds to the 14-pin TSSOP package configuration as documented in the ordering information table. Confirm that the internal fixed gain of -1.5V/V aligns with system requirements, distinguishing it from the adjustable gain variant. Ensure compatibility with the specified 4.5V to 5.5V supply range and thermal dissipation limits for the selected enclosure.

Audio Amplifiers Selection Notes

Select this component when board space conservation is critical due to the elimination of large output coupling capacitors. The fixed -1.5V/V gain simplifies external resistor networks compared to adjustable variants. Verify that the 14-pin TSSOP footprint fits the design constraints and that the 3.5mA quiescent current meets power budget requirements for the target application.

Audio Amplifiers Part Context

This part belongs to the MAX9728 family of DirectDrive stereo headphone amplifiers manufactured by Analog Devices Inc./Maxim Integrated. The family includes variants with adjustable or fixed gains and different package options such as TQFN and TSSOP. These devices are designed for portable electronics requiring high audio fidelity with minimal external components.
