MAX9700AEUB+T

Audio Amplifiers Overview

The MAX9700AEUB+T 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 spread-spectrum modulation scheme that eliminates the need for output filters. The device operates on a 2.5V to 5.5V supply, offers a fixed gain of 6dB (suffix A), and includes integrated click-and-pop suppression, short-circuit protection, and thermal overload protection.

Audio Amplifiers Feature Summary

• Filterless operation utilizing proprietary modulation to pass FCC radiated emissions standards without external LC filters
• Spread-spectrum mode reduces EMI-radiated emissions by 5dB compared to conventional methods
• Fully differential architecture with comprehensive click-and-pop suppression for clean startup and shutdown
• Low-power shutdown mode reducing current consumption to 0.1µA

Audio Amplifiers Applications

• Cellular Phones
• PDAs
• MP3 Players
• Portable Audio

Audio Amplifiers Procurement Notes

Verify the specific suffix AEUB+T against the manufacturer's official ordering guide to confirm the 10-pin µMAX package and 6dB internal gain configuration. Ensure compatibility with system voltage requirements between 2.5V and 5.5V. Check for end-of-life status or discontinuance notifications prior to final design commitment.

Audio Amplifiers Selection Notes

Select this component for space-constrained portable designs requiring high efficiency and minimal external components. The 10-pin µMAX package suits applications needing a compact surface-mount solution. Choose based on required gain (6dB for 'A' variant) and the necessity for differential input noise immunity in RF-dense environments like mobile phones.

Audio Amplifiers Part Context

Part of the MAX9700 family of filterless Class D amplifiers designed to combine AB-class performance with D-class efficiency. The family includes variants with different gains and packages, such as TDFN and UCSP options, all sharing the core low-EMI modulation technology and protection features.

Audio Amplifiers Replacement Considerations

Direct substitutes within the same family include MAX9700BEUB+T (12dB gain) and MAX9700CEUB+T (15.6dB gain). Cross-package equivalents are available, such as MAX9700AETB+T (TDFN) and MAX9700AEBC+T (UCSP), maintaining identical electrical characteristics.
