The MISCO 38067 is a compact and reliable audio amplifier board designed to deliver consistent performance as a 2 channel audio amplifier in space-constrained applications. With dimensions of only 64 × 57 × 15 mm, this PCB style amplifier is particularly well suited for products where efficient layout and straightforward mounting are essential. At the same time, its high-efficiency Class D architecture helps reduce heat generation, ensuring stable operation even in enclosed environments. As a result, this two channel audio amplifier board is an excellent choice for OEM and embedded audio systems that require dependable performance in a small footprint.
In addition, the amplifier is designed to work with analog audio inputs and functions as a versatile two channel amplifier, supporting both 4 ohm and 8 ohm speaker loads. Depending on supply voltage and impedance, it delivers up to 12.5 W per channel, while a 100 dB signal-to-noise ratio and a wide frequency response from 28 Hz to 20 kHz provide clean, full-range sound. Furthermore, the board-level format and standard connectors for line input and speaker output allow this two channel audio amplifier to be easily integrated into finished products without the need for additional amplification stages, simplifying overall system design.
