MAX9700CEBC+T

Audio Amplifiers Overview

The MAX9700CEBC+T is a mono Class D audio power amplifier from Analog Devices/Maxim Integrated, housed in a 12-bump UCSP package. It delivers 1.2W into an 8Ω load with over 90% efficiency. The device operates on a single supply voltage ranging from 2.5V to 5.5V and features a fixed quiescent current of 4mA. Internal gain is set at 15.6dB for the 'C' variant. It includes spread-spectrum modulation to reduce EMI, differential inputs, and comprehensive click-and-pop suppression.

Audio Amplifiers Feature Summary

• Filterless architecture eliminates the need for external output LC filters
• Spread-spectrum mode reduces radiated emissions by 5dB compared to conventional methods
• Fully differential input structure improves noise immunity and allows DC coupling
• Integrated click-and-pop suppression prevents audible transients during startup and shutdown

Audio Amplifiers Applications

• Cellular phones
• Portable MP3 players
• Personal Digital Assistants (PDAs)
• Portable audio devices

Audio Amplifiers Procurement Notes

Verify the specific suffix 'CEBC+T' against official manufacturer documentation to confirm the exact package type, temperature range, and internal gain setting. Ensure compatibility with the required 12-bump UCSP footprint and check for any recent product change notices or end-of-life status updates prior to finalizing procurement plans.

Audio Amplifiers Selection Notes

Select this component when board space is limited due to its compact UCSP packaging. It is suitable for battery-powered applications requiring high efficiency and low quiescent current. The internal 15.6dB gain configuration minimizes the need for external resistors. Verify that the system clock requirements align with the SYNC pin capabilities if synchronization is needed.

Audio Amplifiers Part Context

This part belongs to the MAX9700 family of filterless Class D amplifiers. Variants within the family differ primarily in internal gain settings (A: 6dB, B: 12dB, C: 15.6dB, D: 20dB) and physical packages. The CEBC+T designation specifically indicates the 15.6dB gain version in the 12-bump UCSP package.

Audio Amplifiers Replacement Considerations

Direct substitutes include other MAX9700 variants such as MAX9700BEBC+T or MAX9700AEBC+T, provided the gain difference is acceptable. Alternative packages like TDFN or μMAX are available but require layout changes.
