Maxim Integrated MAX97220BETE+ Differential Input DirectDrive Line Drivers/Headphone Amplifiers

The MAX97220BETE+ is a high-performance, differential input, DirectDrive® line driver and headphone amplifier from Maxim Integrated. This integrated circuit is designed to provide a high-quality audio experience for a wide range of applications. It is suitable for portable music players, smartphones, tablets, laptops, and other devices that require a compact, efficient, and high-fidelity audio solution.

The MAX97220BETE+ features Maxim Integrated's proprietary DirectDrive technology, which eliminates the need for large DC-blocking capacitors, thereby saving space and improving audio performance. This technology allows the amplifier to directly drive the headphones, providing a cleaner sound with lower distortion and a wider dynamic range.

This device operates from a single 2.7V to 5.5V power supply, making it versatile for use in both battery-powered and line-powered applications. The MAX97220BETE+ offers a high output power of up to 130mW per channel into a 32Ω load, ensuring ample volume and clarity for a premium listening experience.

The differential inputs of the MAX97220BETE+ help to reject common-mode noise, providing improved signal integrity and reduced susceptibility to interference. This feature is particularly beneficial in environments with high levels of electromagnetic noise, such as mobile phones and wireless devices.

With its low 0.003% total harmonic distortion plus noise (THD+N) and 120dB power-supply rejection ratio (PSRR), the MAX97220BETE+ delivers crystal-clear audio output. Additionally, the device incorporates comprehensive click-and-pop suppression to minimize noise during power-up and shutdown transitions.

The MAX97220BETE+ comes in a compact, 16-pin TQFN package with an exposed pad, which aids in thermal management and allows for a smaller footprint on the PCB. Its built-in thermal overload protection ensures reliable operation under a variety of conditions.

For designers and audio enthusiasts looking for an audio amplifier that provides high-quality sound with minimal external components, the MAX97220BETE+ from Maxim Integrated is an excellent choice. It combines performance, efficiency, and compactness to meet the rigorous demands of modern audio applications.
