Amazing audio performances in a tiny package. The TSTHX-88 headphone amplifier IC delivers an immersive listening experience with impressive battery life. Create a wireless headphone experience that is like being there.
The THX AAA™ amplifier is THX’s first foray into the arena of component technologies. It reduces harmonic, intermodulation, and crossover distortions by 20-100x for an unbelievably realistic and fatigue-free listening experience, and reduces power consumption by a factor of 10 for incredibly long battery life. THX AAA™ accomplishes this using a patented topology to cancel conventional distortion mechanisms and reduce bias current. THX AAA™ improves audio fidelity, shrinks battery size and extends playtime. The flagship THXAAA-0 amplifier boasts nearly un-measurable distortion of -137 dB, high output power of 63 mW, and only 5 mW of quiescent power consumption.
Leveraging THX AAA™, the TSTHX-88 will be the industry’s best headphone amplifier ASIC. TSTHX-88 reduces harmonic, intermodulation, and crossover distortions by 20x to less than 0.00005% for the absolute best audio fidelity, and uses near-zero bias current and advanced Class G power management to dramatically decrease power consumption by 10x for incredibly long battery life. The TSTHX-88 also produces powerful performance with any headphone type, outputting a formidable 2.2 Volts rms into 300 Ohms and 2 x 63 milli-Watts into 16 Ohms. TSTHX-88 enables exquisite sound quality, smaller batteries, extended playtime and is perfect for products such as digital and wireless headphones, noise-canceling headphones, VR headsets, portable media players, and premium notebooks and tablets.TSTHX-88 IC Product Page
The AAA in THX AAA stands for Achromatic Audio Amplifier.
Achromatic means “without color.” In the transmission of light, achromatic relates to a lens system that transmits light without seperating it into constituent colors. An achromatic lens transmits light without adding, attenuating or distorting the light. The light is transmitted with its orignal fidelity.
The short answer is an Achromatic Audio Amplifier transmits the original audio in its purest possible form without distorting or ‘coloring’ the audio.
Audio amplifiers can be implemented with a variety of topologies. The Class A amplifier is a luxury. Class A amplifiers deliver great sound but they are big, expensive and burn lots of power.
People think Class D amplifiers are a recent innovation. Class D, in fact, goes back to the late 50s and 60s and the introduction of solid state technology.
THX requirements for ultra low noise, ultra low distortion, and ultra low power lead them to the development of a completely different amplifier technology. THX researched the ways an amplifier generates heat when playing music. They set a goal of developing an amplifier that was tiny, low power and still approached the audio fidelity of a Class A amplifier.
In 2006, THX started it’s AAA amplifier research. This research was not about reinventing the amplifier. Instead, THX focused on the shortcommings and physics of heat and noise generation in the amplifier and developed a technology to deal with improving both. A THX AAA can stay within a fraction of its low level distortion right up to with 1dB of the amplifier’s full output.
The AAA delivers 100x reduction distortion with major improvements in signal to noise ratio.
THX is about taking the listener or viewer as close as possible to the original. The craftsmanship that goes into a soundtrack is seldom heard by the end customer and THX wants to see how we might improve the transmission from source to end user to make that possible. The development of AAA was part of that vision. Deliver the performance of a Class A amplifier without the heat and weight.
