USound GmbH (Graz, Austria) has developed a high-performance low power linear audio amplifier than can boost the battery life of TWS, hearing aids, and smart glasses.

Tarvos 1.0 UC-P3010 is designed to drive USound MEMS speakers at up to 40kHz and has a quiescent current of 0.9 mA.

USound claims that when combined with the Tarvos 1.0 UC-P3010, USound MEMS speakers take up 50 percent less space, use 80 percent less energy, and provides a wider audio frequency range compared to voice coil-based audio solutions. Additionally, the analog audio input of the amplifier is compatible with the analog outputs of the latest Bluetooth solutions.

“USound MEMS speakers are designed to reduce system costs, to facilitate the manufacturing process, and to improve the reliability of hearables and wearables. With this new ASIC audio amplifier, we can design ultra-compact audio modules, including MEMS tweeter, woofers, and amplifiers can be produced, taking modularization to the next level,” said Andrea Rusconi Clerici, CTO of USound, in a statement.

The Tarvos 1.0 UC-P3010 is sampling to key customers and will be in mass production in 2023.
