Key Features
- 15 W per channel Class D stereo output in filter-free topology, eliminating external LC output filters and reducing BOM cost
- SpeakerGuard short-circuit and over-temperature protection safeguards connected speakers and ensures system reliability
- 36 dB fixed gain with 22 kHz audio bandwidth across -40°C to +85°C operating range, suitable for automotive and consumer audio equipment
Applications
The HPA01070PWPR is designed for portable speakers, soundbars, and automotive infotainment systems that require high efficiency stereo audio amplification without output filters. Its 15 W per channel output power and filter-free Class D architecture make it ideal for battery-powered and USB-powered speaker docks where PCB space and power dissipation are critical constraints. The SpeakerGuard feature and wide -40°C to +85°C temperature range also make it suitable for ruggedized audio systems in industrial and automotive environments.

Frequently Asked Questions
How does the filter-free Class D topology of the HPA01070PWPR simplify PCB design compared to traditional amplifiers?
The HPA01070PWPR uses a filterless Class D architecture that drives speakers directly without external LC output filters, saving 4 to 8 passive components and reducing PCB area by up to 30%. The 15 W per channel output is delivered via PWM switching, which the speaker's voice coil inherently filters, making this approach effective for speakers with leads shorter than approximately 30 cm.
What protection features does SpeakerGuard provide in the HPA01070PWPR for a stereo speaker system?
SpeakerGuard in the HPA01070PWPR continuously monitors both output channels for short-circuit conditions and over-temperature events. If a speaker lead is shorted to ground or VCC, the device shuts down the affected channel within microseconds to prevent damage. The thermal shutdown activates at approximately 150°C junction temperature, with an automatic restart once the device cools below the hysteresis threshold.
In which audio applications does the 36 dB gain and 22 kHz bandwidth of the HPA01070PWPR meet full-range audio requirements?
The HPA01070PWPR's 36 dB gain and 22 kHz bandwidth cover the full audible frequency range from 20 Hz to 20 kHz with margin, making it suitable for portable Bluetooth speakers, soundbars, and TV audio systems requiring stereo output. The 15 W per channel into 4-ohm or 8-ohm speakers is sufficient for home audio and small venue applications without additional power stages.
