UC-P3010-H24

Overview

The UC-P3010-H24 is a Class H piezo speaker ASIC linear audio amplifier from USound GmbH, designed for 3.6 V Li-Ion battery supplies. It features an analog audio input compatible with common Bluetooth SoCs and supports frequency ranges from 20 Hz to 80 kHz. The device delivers up to 27 VPP output voltage within this range, utilizing an integrated DC-DC boost converter. Available gains are 18, 24, and 30 dB, with the H24 variant configured for 24 dB gain. It draws less than 1 mA quiescent current and offers THD+N of 103 dB. Packaged in a compact 16-ball 2x2 mm² WLCSP, it includes built-in DC bias voltage sourcing and supports load capacitance up to 50 nF.

Feature Summary

• Class H linear amplification architecture optimized for low power consumption with sub-mA quiescent current draw.
• Integrated DC-DC boost converter enabling high-voltage output swing suitable for driving capacitive MEMS speakers.
• Built-in DC bias voltage source to enhance performance when paired with USound Conamara series MEMS transducers.
• Analog audio input interface directly compatible with standard Bluetooth audio system-on-chip outputs.

Applications

• True wireless earphones
• Over-the-counter hearing aids
• Wideband ultrasonic applications

Procurement Notes

Verify that the specific ordering suffix corresponds to the required gain configuration and target speaker series. The UC-P3010-H24 is specifically configured for the Conamara series at 24 dB gain. Ensure compatibility with the intended MEMS speaker model, such as UA-C0503-3T or UA-C0603-3F, as listed in the official ordering information. Confirm package type and pinout alignment during integration planning.

Selection Notes

Select this component when integrating USound Conamara series MEMS speakers requiring a 24 dB fixed gain configuration. It is suitable for designs powered by 3.6 V sources where low quiescent current is critical. Consider the integrated boost converter capabilities if high output voltage swing is needed for wideband or ultrasonic operation. Ensure the application schematic accounts for the recommended external components for the boost converter and input/output filtering.

Part Context

This part belongs to the Tarvos 1.0 family of ASIC linear audio amplifiers developed by USound GmbH. The Tarvos series is engineered specifically for driving piezoelectric and MEMS speakers in portable audio devices. The UC-P3010-H24 represents a specific configuration within this family, tailored for the Conamara speaker line with a fixed 24 dB gain setting, distinguishing it from other variants like the G-series or different gain options.

Replacement Considerations

Official substitutes include UC-P3010-H18 (18 dB gain) and UC-P3010-H30 (30 dB gain) for the same Conamara series. For Ganymede series speakers, consider UC-P3010-G18, UC-P3010-G24, or UC-P3010-G30. Custom configurations are available via UC-P3010 but may involve NRE costs.
