MAX9723CEBE+T

Audio Amplifiers Overview

The MAX9723CEBE+T is a stereo DirectDrive headphone amplifier from Analog Devices/Maxim Integrated, designed for portable audio applications. It operates on a single 1.8V to 3.6V supply and delivers 62mW into a 16Ω load with 0.006% THD+N. The device features an integrated 32-level volume control, software-enabled BassMax, and I2C/SMBus interface. It utilizes UCSP-16 packaging (2mm x 2mm x 0.62mm) and functions within a -40°C to +85°C temperature range.

Audio Amplifiers Feature Summary

• DirectDrive architecture eliminates bulky DC-blocking capacitors by generating an internal negative supply via a charge pump.
• Integrated 32-level digital volume control and software-enabled BassMax circuitry accessible through the I2C/SMBus-compatible interface.
• Industry-leading click-and-pop suppression ensures minimal audible transients during power-up and shutdown transitions.
• Headphone outputs are protected against ±8kV HBM ESD strikes and include short-circuit and thermal-overload safeguards.

Audio Amplifiers Applications

• PDA Audio
• Portable CD Players
• Mini Disc Players
• MP3-Enabled Cellular Phones
• MP3 Players

Audio Amplifiers Procurement Notes

Verify the specific suffix 'CEBE' corresponds to the UCSP-16 package and the required gain configuration (+6dB) before procurement. Confirm that the ordering code matches the exact slave address requirements for your system bus topology. Ensure compatibility with the specified 1.8V to 3.6V single-supply voltage range for your target application.

Audio Amplifiers Selection Notes

Select this component when board space is limited due to its compact UCSP-16 footprint. Choose this model if a maximum gain of +6dB is required, distinguishing it from the 0dB variants. Consider this part for designs needing digital volume adjustment and bass boost without external potentiometers or complex analog circuits.

Audio Amplifiers Part Context

This component belongs to the MAX9723 family of stereo DirectDrive headphone amplifiers. It shares core architectural features with other variants in the series but differs in maximum gain settings and physical packaging options. The family is engineered to reduce external component counts while maintaining high audio fidelity in mobile devices.

Audio Amplifiers FAQ

How does the DirectDrive architecture benefit the design?

It creates a ground-referenced output from a single supply, eliminating the need for large DC-blocking capacitors and saving significant board space.

What is the purpose of the BassMax feature?

BassMax boosts the low-frequency response to compensate for the natural attenuation found in small headphones, improving overall audio reproduction.
