Infineon develops first self-contained Raspberry Pi audio HAT board

By Michelle Froese

Infineon Technologies has developed the world’s first fully self-contained Raspberry Pi audio amplifier HAT (Hardware attached on Top) board. It offers high-definition audio at boom box power levels in a small form factor.

The Infineon proprietary multi-level technology ensures minimum size and consumption, state of the art power efficiency, and HD audio quality for Raspberry Pi users and makers. Target field of use are active speakers with wireless music streaming.

The board (KIT_40W_AMP_HAT_ZW) is compatible with Raspberry Pi Zero W and Raspberry Pi 3 and 4. It leverages the MERUS multi-level class D amplification enabled by the MERUS MA12070P amplifier, which allows for filter-free amplifier design that does not need to use a filter-coil at the output filter. This reduces significantly the BOM cost and enables PCB area reduction.

Additionally, the board scores high-output power in small form factor up to 40 W instantaneous peak power at 4 Ohm. The solution offers best-in-class efficiency and playback time up to 20 hours with a ~6700 mAh power bank. There is no need for additional power supplies — only a single 5 V/2.5 A USB power supply is required for both the Raspberry Pi and the HAT.

For a quick and easy audio system set-up the board is compatible with the main 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.
