Introducing Tarvos 1.2 UC-P3012, USound’s Newest Audio Amplifier for MEMS Speakers
In the evolving landscape of portable and wearable devices, audio components face increasing demands: more power efficiency, smaller footprints, and superior audio quality. Built upon the success of the original Tarvos 1.0 audio amplifier, Tarvos 1.2 UC-P3012 offers improved efficiency, higher output voltage, and reduced B.O.M.—all while reducing footprint.
More Audio Power, Less Space and Energy
USound’s MEMS speakers represent a major leap in form factor, bandwidth, and durability. To enable USound’s MEMS speakers to reach their full acoustic output, USound engineered Tarvos to deliver the 31 VPP required.
The improvements in Tarvos 1.2 UC-P3012 target power-sensitive and size-constrained applications, such as TWS earbuds or hearing aids. The market needed a compact, efficient, high-voltage amplifier that successfully preserved battery life and audio quality.
Enabling an Outstanding MEMS Speaker Audio Performance
With Tarvos 1.2 UC-P3012, we deliver on that need—and then some more. This new version of Tarvos increases the maximum output voltage to 31 VPP while reducing the quiescent current to just 0.8 mA, thereby improving energy efficiency and extending battery life.
Tarvos 1.2 UC-P3012 brings:
- Improved SNR: above >104.8 dB for cleaner, clearer audio across use cases.
- Minimal THD (<0.3%): has a minimal increase in THD, carefully balanced to maximize audio fidelity, ensuring that the overall sound quality remains top-notch
- ‑1 dB Bandwidth up to 80 kHz: to support high-resolution audio and ultrasonic applications.
- Smaller PCB footprint: with fewer external components for easier system integration.
- Less quiescent battery current: improving energy efficiency.
Designed for Performance, Built for Integration
Tarvos 1.2 UC-P3012’s compact form factor and low-power operation make it ideal for TWS earbuds, OTC and hearing aids, AR glasses, MedTech, IoT audio nodes, and portable communication devices. It offers exceptional electro-acoustic efficiency in the critical 1–10 kHz band, where voice, music, and audio cues live. That means:
- Sharper voice clarity in calls and smart assistants.
- Longer playback time in wearables and portable devices.
But Tarvos 1.2 UC-P3012 does not stop in the traditional 20 Hz -20 kHz bandwidth, reaching up to 80 kHz with -1 dB, enabling Hi‑Res and ultrasound applications alike. This translates to sharper audio and paves the way for new possibilities in wideband ultrasound applications, where the typical transducer works within a very narrow frequency range:
- There is no need to tune the audio frequency to specific resonance frequencies.
- No need to narrow the application to one operation frequency.
- Reduce R&D effort and manufacturing costs.
At USound, we believe that NextGen audio devices start with easy integration. Tarvos 1.2 UC-P3012 is more than an analog audio amplifier ASIC—it’s an enabler of design freedom, product innovation, and acoustic excellence.
Whether you’re building cutting-edge consumer electronics or specialized industrial devices, Tarvos 1.2 UC-P3012 plus USound’s MEMS speakers bring:
- Improvement in high‑SPL audio, clean and distortion-free.
- A crystal‑clear sound for every beep, voice, and tone your product needs to deliver.
- Simplified B.O.M. to reduce the final product cost.
