Audio Amplifiers datasheet and documents for MAX9724AEUD+

MAX9724AEUD+

Audio Amplifiers Overview

The MAX9724AEUD+ 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 2.7V to 5.5V supply, consuming 3.5mA quiescent current. It features adjustable gain, <0.1µA shutdown current, and 80dB PSRR at 1kHz. The package is a 12-bump UCSP (1.5mm x 2mm).

Audio Amplifiers Feature Summary

DirectDrive architecture eliminates bulky DC-blocking capacitors by generating an internal negative supply.
Integrated RF noise rejection prevents demodulation of coupled interference on input and supply traces.
Comprehensive click-and-pop suppression circuitry removes audible transients during startup and shutdown.
Low-power shutdown mode reduces current consumption to less than 0.1µA.

Audio Amplifiers Applications

Cellular Phones
MP3 Players
Notebook PCs
Handheld Gaming Consoles

Audio Amplifiers Procurement Notes

Verify the specific suffix 'EUD' against official manufacturer documentation to confirm the exact package type and temperature range. Ensure compatibility with the required gain configuration for the MAX9724A variant. Confirm lead-free status and RoHS compliance through the datasheet before procurement.

Audio Amplifiers Selection Notes

Select this component for portable designs requiring minimal board space due to the compact UCSP package. The adjustable gain feature allows flexibility in system design compared to fixed-gain variants. Ensure the application benefits from the elimination of external coupling capacitors to reduce overall component count and height.

Audio Amplifiers Part Context

This part belongs to the MAX9724 family of low-power stereo headphone amplifiers. It shares the core DirectDrive technology with the MAX9724B but offers externally adjustable gain. The family targets battery-powered audio applications where size and power efficiency are critical constraints.
