UC-P3010-H18

Overview

The UC-P3010-H18 is a Class H linear audio amplifier designed for 3.6 V supplies, featuring an integrated DC-DC boost converter and DC bias source. It supports gains of 18, 24, or 30 dB with a frequency range of 20 Hz to 80 kHz. The device delivers up to 27 VPP output voltage, handles loads up to 50 nF, and achieves THD+N of 103 dB. Quiescent current is under 1 mA, and it operates within -20°C to 125°C junction temperature in a 2x2 mm WLCSP package.

Feature Summary

• Class H amplification architecture with integrated DC-DC boost converter
• Built-in DC bias voltage source optimized for MEMS speakers
• Low quiescent current consumption for battery-powered devices
• High signal-to-noise ratio with low total harmonic distortion

Applications

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

Procurement Notes

Verify the specific suffix configuration (H18) matches the required gain and speaker series compatibility before ordering. Confirm that the application schematic aligns with the H-configuration design requirements. Ensure external components meet the specified voltage and capacitance ratings for stable operation.

Selection Notes

Select this component when driving USound Conamara series MEMS speakers requiring high voltage swing from a single low-voltage supply. The integrated boost converter eliminates the need for external high-voltage generation circuits. Verify that the system's analog audio input levels are compatible with the differential input specifications.

Part Context

This part belongs to the Tarvos 1.0 family of ASIC linear audio amplifiers manufactured by USound GmbH. It is specifically configured for the Conamara series of MEMS speakers with a fixed 18 dB gain setting. The device integrates power management and amplification functions into a compact footprint suitable for space-constrained wearable electronics.

Replacement Considerations

Direct substitutes are not listed in official documentation. Alternative configurations include UC-P3010-G18 for Ganymede series speakers or variants with different gain settings (UC-P3010-H24, UC-P3010-H30). Custom configurations may be available through USound directly.

FAQ

What is the maximum load capacitance supported?

The device supports a load capacitance up to 50 nF for unconditional stability.

How does the device handle low battery conditions?

The LBAT sensing circuit detects if the battery level drops below 3.0 V and automatically reduces the amplifier’s gain by 6 dB to conserve current.

Is the device compatible with standard Bluetooth SoCs?

Yes, its analog audio input is compatible with the analog audio outputs of most common Bluetooth audio SoCs.
