Applications
The MAX9723DETE+T is designed for portable audio products such as smartphones, MP3 players, and tablet computers that require a high-quality stereo headphone amplifier with software volume control and bass enhancement. Its DirectDrive topology removes the need for output DC-blocking capacitors, reducing BOM cost and PCB area in slim handheld devices. It is also used in docking stations, portable gaming consoles, and notebook audio subsystems where a low-power, feature-rich stereo headphone amplifier with I2C control simplifies system integration.

Frequently Asked Questions
How does DirectDrive architecture in MAX9723DETE+T reduce component count versus a conventional headphone amplifier?
DirectDrive generates a negative supply internally from the single positive rail, allowing the output to swing around 0 V without a DC offset. This eliminates the 2 large DC-blocking electrolytic capacitors (typically 100 µF to 470 µF each) required by conventional AC-coupled Class AB headphone amplifiers, saving at least 2 components and reducing audio low-frequency roll-off below 20 Hz in a 32 Ω headphone load.
What I2C address options and control resolution does MAX9723DETE+T offer for volume adjustment?
The MAX9723DETE+T includes an I2C interface for digital volume control, allowing the host processor to set gain in discrete steps across a programmable range typically spanning 0 dB to -80 dB or more. I2C operates at standard 400 kHz fast-mode speeds, giving designers firmware-controlled volume management without a mechanical potentiometer, which reduces wear failure modes in portable consumer products with an expected life of 3 to 5 years.
What audio bandwidth does MAX9723DETE+T provide, and is it sufficient for high-resolution audio playback?
The MAX9723DETE+T has a nominal bandwidth of 22 kHz, covering the standard human audible frequency range from 20 Hz to 20 kHz. For standard 44.1 kHz or 48 kHz PCM audio sources such as CD or streaming, this 22 kHz bandwidth is fully adequate. For 96 kHz or 192 kHz high-resolution audio formats requiring extended bandwidth above 40 kHz, a wider-bandwidth amplifier would be needed in the signal chain.
What does BassMax enhancement do, and in which headphone impedance range is it most effective?
BassMax is a bass-boost feature integrated into MAX9723DETE+T that electronically boosts low-frequency output below approximately 200 Hz to compensate for typical headphone bass roll-off. It is most effective with low-impedance headphones in the 16 Ω to 32 Ω range, which are standard for consumer earbuds and over-ear headphones. The effect can be enabled or disabled via I2C, allowing end-product firmware to offer a user-selectable bass enhancement toggle.
Is MAX9723DETE+T REACH-compliant for export to EU consumer electronics markets, and what packaging format is available?
Yes, the MAX9723DETE+T carries a REACH Compliance Code of Compliant, confirming it meets EU REACH SVHC substance restrictions for consumer electronics. The TE+T suffix denotes tape-and-reel packaging in the 16-pin LFCSP 4 mm x 4 mm x 0.75 mm format, suitable for automated SMT assembly in high-volume smartphone and portable audio production lines with typical reel quantities of 2,500 units.
