Audio Amplifiers datasheet and documents for MAX9724CETC+T

MAX9724CETC+T

Audio Amplifiers Overview

The MAX9724CETC+T is a stereo headphone amplifier utilizing DirectDrive architecture for single-supply operation. It operates from a 2.5V to 5.5V supply with a typical quiescent current of 3.5mA. The device delivers up to 60mW per channel into a 32Ω load and features low 0.02% THD+N. It includes an adjustable gain configuration, integrated click-and-pop suppression, and high PSRR of 80dB at 1kHz. The component is housed in a 12-pin thin QFN (3mm x 3mm) package.

Audio Amplifiers Feature Summary

DirectDrive architecture eliminates the need for bulky DC-blocking output capacitors by generating an internal negative rail via a charge pump.
Low RF susceptibility design prevents demodulation of coupled noise from input and supply traces acting as antennas.
Integrated comprehensive click-and-pop suppression circuitry ensures silent startup and shutdown transitions.
Features a low-power shutdown mode consuming less than 0.1µA to extend battery life in portable applications.

Audio Amplifiers Applications

Cellular phones
MP3 players
Notebook PCs
Handheld gaming consoles
Smart phones

Audio Amplifiers Procurement Notes

Verify the specific suffix ET indicates the 12-pin TQFN-EP package and tape-and-reel delivery format. Confirm that the C variant matches the requirement for externally adjustable gain rather than the internally preset D variant. Ensure compatibility with the required operating temperature range of -40°C to +85°C for the target application environment.

Audio Amplifiers Selection Notes

Select this component when board space is limited due to its compact 12-pin thin QFN footprint. Choose the C version specifically for designs requiring externally adjustable gain through external resistors. Consider the low quiescent current and shutdown capabilities for battery-powered devices where power efficiency is critical.

Audio Amplifiers Part Context

This part belongs to the MAX9724 family of low RF susceptibility DirectDrive stereo headphone amplifiers. It shares architectural similarities with the MAX9724D but differs in gain configuration. The family is designed for portable equipment where minimizing component count and height is essential for modern form factors.
