Maxim Integrated's MAX97220EETE+ Differential Input DirectDrive Line Driver/Headphone Amplifier
The MAX97220EETE+ from Maxim Integrated is a premium-grade differential input DirectDrive line driver and headphone amplifier. This high-performance component is designed to provide a superior audio experience for a wide range of applications. It is housed in a compact 16-pin TQFN package, making it an ideal choice for space-constrained designs.
The MAX97220EETE+ incorporates Maxim's patented DirectDrive technology, which eliminates the need for DC-blocking capacitors, thus reducing the overall component count and saving board space. This technology also ensures a lower output impedance and a more linear frequency response, resulting in a cleaner, more accurate sound reproduction.
With its differential inputs, the MAX97220EETE+ is capable of rejecting common-mode noise, making it particularly well-suited for environments with significant electronic interference. This feature is essential for maintaining audio fidelity in smartphones, tablets, laptops, and other portable devices that operate in electrically noisy conditions.
The device boasts a high output power of up to 130mW into a 16Ω load, ensuring that it can drive a wide range of headphones, from high-impedance audiophile models to low-impedance earbuds. Additionally, the MAX97220EETE+ offers a low 0.00003% total harmonic distortion plus noise (THD+N) and a 110dB signal-to-noise ratio (SNR), which translates to a crystal-clear audio output without unwanted distortion or noise.
For added flexibility, the MAX97220EETE+ features an integrated charge pump that generates a negative supply voltage, allowing for ground-referenced outputs without sacrificing the swing capability. This means the amplifier can provide a full audio dynamic range, even with a single power supply.
Maxim Integrated has designed the MAX97220EETE+ with thermal overload protection and a low quiescent current, ensuring both safety and energy efficiency. Whether you're designing high-end audio equipment or looking for a reliable solution for your portable device's audio system, the MAX97220EETE+ stands out as a top-tier choice for delivering high-quality sound in a tiny footprint.
