MAX9725DETC

Audio Amplifiers Overview

The MAX9725DETC is a Class-AB audio amplifier from the DirectDrive series, designed for low-voltage mobile applications. It operates on a single supply voltage ranging from 0.9V to 1.8V and delivers 25mW per channel into a 16-ohm load. The device features integrated pop-and-click suppression, short-circuit protection, and shutdown functionality. It is housed in a compact 12-UCSP package and supports stereo headphone outputs within an operating temperature range of -40°C to +85°C.

Audio Amplifiers Feature Summary

• DirectDrive architecture eliminates output coupling capacitors for space-efficient designs
• Integrated pop-and-click suppression prevents audible transients during power transitions
• Short-circuit protection safeguards the amplifier under fault conditions
• Shutdown mode minimizes current consumption when the device is not in use

Audio Amplifiers Applications

• Mobile phone headphone amplifiers
• Portable media players
• Personal digital assistants (PDAs)
• MP3 players

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notices, as this specific part number may be discontinued. Ensure the package type matches the design requirements before procurement.

Audio Amplifiers Selection Notes

Select this component for ultra-low voltage operation below 1.8V where capacitor-less output is required. Consider the 12-UCSP package size for tight board space constraints. Evaluate thermal performance at maximum power output relative to the PCB copper area available for heat dissipation.

Audio Amplifiers Part Context

This device belongs to the Maxim Integrated DirectDrive family of audio amplifiers. These components are engineered specifically for battery-powered portable electronics requiring high efficiency and minimal external component count. The series prioritizes sound quality and reliability in compact form factors.

Audio Amplifiers Replacement Considerations

Check for MAX9725 variants with different suffixes indicating alternative packages such as TQFN or UCSP. Verify pin-to-pin compatibility if substituting with other DirectDrive models. Consult official documentation for any functional differences between legacy and updated revisions.
