MAX9700DEUB+T

Audio Amplifiers Overview

The MAX9700DEUB+T is a mono Class D audio power amplifier from Analog Devices/Maxim Integrated. It delivers 1.2W into an 8Ω load with over 90% efficiency, eliminating the need for output filters. The device features differential inputs, integrated click-and-pop suppression, and low quiescent current of 4mA. It operates on a single supply voltage ranging from 2.5V to 5.5V and includes short-circuit and thermal protection. The part is housed in a 10-pin μMAX package and supports fixed-frequency or spread-spectrum modulation modes.

Audio Amplifiers Feature Summary

• Filterless architecture that 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 eliminates audible transients during startup and shutdown

Audio Amplifiers Applications

• Cellular Phones
• PDAs
• MP3 Players
• Portable Audio

Audio Amplifiers Procurement Notes

Verify the specific suffix DEUB corresponds to the 10-pin μMAX package and 20dB gain configuration as defined in the official datasheet ordering information. Confirm RoHS compliance status through the manufacturer's certification documentation prior to integration. Ensure the design accounts for the exposed pad thermal requirements if applicable to the selected package variant.

Audio Amplifiers Selection Notes

Select this component for applications requiring high efficiency and minimal board space due to its filterless operation. The internal gain setting of 20dB for the 'D' variant determines the required input signal level. Consider the 10-pin μMAX package for designs prioritizing surface-mount compatibility with specific footprint constraints over the TDFN or UCSP options.

Audio Amplifiers Part Context

This device belongs to the MAX9700 family of low-EMI, filterless Class D audio amplifiers. The family shares core architectural features such as the H-bridge output stage and modulation schemes. Variants within the series differ primarily by internal gain settings (A, B, C, D) and physical packaging options (TDFN, μMAX, UCSP).

Audio Amplifiers Replacement Considerations

Cross-reference with other MAX9700 variants sharing the same μMAX package but different gain settings (e.g., MAX9700BEUB+) if system gain requirements change. Verify pinout compatibility before substituting.
