Maxim Integrated MAX9723DETE+ Stereo Headphone Amplifier

The MAX9723DETE+ from Maxim Integrated is a high-performance, low-distortion stereo headphone amplifier that is designed to provide a superior audio experience for portable and consumer electronic devices. This efficient integrated circuit is built to drive a wide range of headphones, from low-impedance to high-impedance models, ensuring compatibility with virtually any personal audio device.

Featuring DirectDrive® technology, the MAX9723DETE+ eliminates the need for large DC-blocking capacitors, thus saving space and cost while also improving low-frequency audio fidelity. The amplifier operates from a single 2.7V to 5.5V supply, making it an excellent choice for battery-powered applications where power efficiency is critical.

The device offers a high level of integration, with built-in click-and-pop suppression that minimizes noise during power-up and shutdown sequences. Users will appreciate the smooth, pop-free experience when starting or stopping their audio playback. Additionally, the MAX9723DETE+ includes comprehensive circuit protection features such as short-circuit and thermal overload protection, ensuring reliable performance and longevity.

With an output power of up to 130mW per channel into a 16Ω load, the MAX9723DETE+ can deliver loud, clear sound without distortion. It also boasts a low 0.003% total harmonic distortion plus noise (THD+N) at 1kHz, which contributes to its high-fidelity audio reproduction. The device's high 100dB power-supply rejection ratio (PSRR) means that it performs well even in environments with fluctuating power supplies, maintaining a consistent audio quality.

The MAX9723DETE+ comes in a compact, 16-pin TQFN-EP (5mm x 5mm) package, making it suitable for space-constrained applications. Its small footprint and high level of functionality make it an ideal choice for portable music players, smartphones, tablets, laptops, and other devices where premium sound quality and space efficiency are desired.

Whether for personal or professional use, the Maxim Integrated MAX9723DETE+ stereo headphone amplifier is engineered to meet the needs of audiophiles and casual listeners alike, delivering exceptional audio performance in a small and efficient design.
