Audio Amplifiers datasheet and documents for MAX9723AETE+
Audio Amplifiers Overview
The MAX9723AETE+ is a stereo Class AB DirectDrive headphone amplifier from Analog Devices/Maxim Integrated. 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 integrated 32-level volume control, software-enabled BassMax bass boost, and I²C/SMBus interface. It includes industry-leading click-and-pop suppression, ±8kV HBM ESD protection, and short-circuit/thermal overload protection. Available in a 16-pin TQFN package, it functions over an extended temperature range of -40°C to +85°C.
Audio Amplifiers Feature Summary
- DirectDrive architecture eliminates bulky DC-blocking capacitors by generating a ground-referenced output from a single supply.
- Integrated digital volume control provides 32 discrete levels via an I²C-compatible serial interface.
- Software-controlled BassMax circuitry boosts low-frequency response to compensate for headphone limitations.
- Comprehensive protection includes ±8kV HBM ESD protection, thermal shutdown, and short-circuit safety.

Audio Amplifiers Procurement Notes
Verify the specific suffix 'A' indicates a maximum gain of 0dB when selecting this component. Confirm the 'ETE+' designation corresponds to the 16-pin Thin QFN package variant rather than the UCSP option. Ensure the design supports the required I²C pull-up resistors and charge-pump capacitors as specified in the official datasheet for proper operation.
Audio Amplifiers Selection Notes
Select the MAX9723AETE+ for applications requiring a 0dB maximum gain configuration within the DirectDrive family. This part is suitable for space-constrained portable audio systems where eliminating large output capacitors is critical. Consider the alternative MAX9723B/C/D variants if different gain settings or I²C addresses are needed for multi-device bus configurations.
Audio Amplifiers Part Context
This component belongs to the MAX9723 series of stereo DirectDrive headphone amplifiers. The series is designed for portable audio devices where board space and power efficiency are paramount. The 'A' suffix distinguishes it from other gain variants within the same functional family, while the 'ETE+' suffix specifies the surface-mount TQFN packaging and lead-free compliance.

Audio Amplifiers FAQ
How does the DirectDrive architecture benefit the system design?
It creates a ground-referenced output using an internal charge pump, eliminating the need for large external DC-blocking capacitors, which saves board space and improves low-frequency response.
What is the function of the BassMax feature?
BassMax is a software-enabled bass boost that compensates for the poor low-frequency reproduction of typical headphones by increasing amplifier gain at low frequencies.
