Infineon’s proprietary multilevel technology cuts size and power consumption to provide HD audio quality for the Raspberry Pi.
The KIT_40W_AMP_HAT_ZW board is compatible with Raspberry Pi Zero W and Raspberry Pi 3 and 4. The HAT is built around Infineon’s MERUS multilevel class D amplification technology in the form of the company’s MERUS MA12070P amplifier. The amplifier is designed for filter-free amplifier design with no need for the filter-coil at the output filter to reduce BoM, cots and allow smaller PCB designs. The board provides up to 40 W instantaneous peak power at 4 Ohm. It is efficient enough to offer up to 20 hours playback time with a ~6700 mAh power bank. Only a single 5 V/2.5 A USB power supply is required to power the Raspberry Pi and the HAT.
The board is compatible with Linux distributions such as Raspbian, Volumio, moOde Audio or JustboomPlayer. Dual-channel bridge-tied load (BTL) or single-channel parallel bridge-tied load (PBTL) configurations for Multiroom, TWS, or subwoofer applications are also possible.
