MAX9700AEUB+

Audio Amplifiers Overview

The MAX9700AEUB+ is a mono Class D audio power amplifier from Analog Devices/Maxim Integrated, housed in a 10-pin µMAX package. It delivers 1.2W into an 8Ω load with over 90% efficiency and features a low-EMI modulation scheme that eliminates the need for output filters. The device operates on a 2.5V to 5.5V supply, offers a gain of 6dB, and includes integrated click-and-pop suppression, short-circuit protection, and thermal overload protection.

Audio Amplifiers Feature Summary

• Filterless architecture passes FCC radiated emissions standards without external LC components
• Spread-spectrum mode reduces EMI-radiated emissions by 5dB compared to conventional methods
• Fully differential input architecture minimizes common-mode noise pickup
• Integrated click-and-pop suppression prevents audible transients during startup and shutdown

Audio Amplifiers Applications

• Cellular Phones
• PDAs
• MP3 Players
• Portable Audio

Audio Amplifiers Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to limited availability or discontinuance notices. Confirm package integrity and pin alignment against the 10-pin µMAX specification before integration. Ensure design compatibility with the specified voltage range and thermal requirements.

Audio Amplifiers Selection Notes

Select this model when board space conservation is critical due to its filterless operation and compact µMAX packaging. Choose the AEUB variant specifically for applications requiring a fixed 6dB internal gain setting. Consider the SYNC input if system-wide clock synchronization or spread-spectrum EMI reduction is required.

Audio Amplifiers Part Context

This component belongs to the MAX9700 family of low-EMI, filterless Class D amplifiers. The AEUB suffix denotes the specific gain configuration (6dB) and the 10-pin µMAX surface-mount package. It shares core architectural features with other variants like the TDFN and UCSP packages within the same product line.

Audio Amplifiers Replacement Considerations

Direct replacements include MAX9700AETB+ (TDFN package) and MAX9700AEBC+T (UCSP package). Verify pinout compatibility and thermal dissipation characteristics when substituting between different package types.
