UC-P3010-G18

Overview

The UC-P3010-G18 is a high-voltage ASIC linear audio amplifier from the Tarvos 1.0 series, designed for 3.6 V Li-Ion battery supplies. It features a Class H architecture with an integrated DC-DC boost converter and sub-mA quiescent current draw. The device supports gains of 18, 24, or 30 dB, delivering up to 27 VPP output voltage within a 20 Hz to 80 kHz frequency range. It includes a built-in DC bias source and handles load capacitance up to 50 nF. Packaged in a compact 16-ball 2x2 mm² WLCSP, it offers THD+N of 103 dB and is optimized for driving capacitive loads like USound MEMS speakers.

Feature Summary

• Class H linear amplification with integrated DC-DC boost converter for high-voltage output generation.
• Low power consumption with sub-mA quiescent current draw from a 3.6 V supply.
• Built-in DC bias voltage source specifically optimized for USound MEMS speaker performance.
• Compatible with analog audio outputs of common Bluetooth SoCs via differential input.

Applications

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

Procurement Notes

Verify the specific suffix 'G18' confirms the Ganymede series configuration with 18 dB gain. Ensure compatibility with target MEMS speaker models such as UT-P2020, UT-P2023, or UT-P2016. Confirm that the application design accounts for the required external components, including the Schottky diode and inductor for the boost converter. Validate that the PCB layout adheres to the low-impedance guidelines for the DC-DC section to maintain stability and efficiency.

Selection Notes

Select this component when driving USound Ganymede series MEMS speakers requiring 18 dB fixed gain. It is suitable for applications needing high output voltage swing from a single-cell lithium-ion battery. Consider the G-configuration specifically for rectangular Ganymede speakers. Evaluate the need for the integrated boost converter if peak sound pressure levels exceed standard amplifier capabilities. Ensure the system design supports the 2x2 mm² WLCSP package constraints.

Part Context

This part belongs to the Tarvos 1.0 family of high-voltage ASIC linear audio amplifiers developed by USound GmbH. The UC-P3010 model line provides various gain configurations tailored for different MEMS speaker series. The 'G' suffix denotes the Ganymede series configuration, while '18' specifies the 18 dB gain setting. This family is engineered to replace traditional discrete amplifier solutions in compact wearable audio devices.

Replacement Considerations

Direct substitutes include UC-P3010-G24 and UC-P3010-G30 for higher gain requirements within the same Ganymede series. For Conamara series speakers, consider UC-P3010-H18, UC-P3010-H24, or UC-P3010-H30. Custom configurations are available through the UC-P3010 custom ordering option, subject to NRE costs.
