ASIC Amplifier

ASIC linear audio amplifier

Tarvos 1.0 UC‑P3010 is an ASIC linear audio amplifier to drive USound MEMS speakers. This high-voltage linear audio amplifier features a DC‑DC boost converter and operates from a 3.6 V Li–Ion battery. The analog audio input is compatible with the analog outputs of the most common Bluetooth® audio SoC. Control and setup are optional through an I2C interface.

Low current consumption

Tarvos 1.0 UC‑P3010 exceeds market demands by reaching 0.8 mA quiescent current consumption.

Audio class H amplifier

Tarvos 1.0 UC‑P3010 is based on an audio class H amplifier, with a frequency range of up to 40 kHz, and can drive up to 28 Vpp with a selectable gain of 18 to 30 dB.

Fully differential topology

Tarvos 1.0 UC‑P3010 has fully differential topology, which allows reaching the lowest total harmonic distortion (THD) and high rejection of external noise.

Selectable DC bias voltage

Tarvos 1.0 UC‑P3010 supplies the DC bias voltage required by USound’s MEMS speakers.

Competitive THD

Tarvos 1.0 UC‑P3010 has output THD < 0.2% at maximum output voltage in the whole
frequency range.

Application description

Tarvos 1.0 UC‑P3010 is the ideal solution to develop MEMS speakers-based audio products, including true wireless earbuds (TWS), audio glasses, over-the-counter (OTC) hearing aids, and AR/VR glasses.
