This high-quality dual channel Class-D audio amplifier board is capable of delivering 2W per channel of output power into a 4 ohm load. A PAM's PAM8803 IC offers ultra-low total harmonic distortion and noise, allowing it to deliver outstanding sound reproduction. Especially suitable for small speakers with an impedance of 4 or 8 ohms. This board can be powered by an external DC supply (4.5V to 12V) via a power port, 2.5V to 4.0V DC via a terminal block, or 2 to 3 AA batteries. Audio signal is input by a 2510 connector or 3.5 mm headphone jack, and volume control is adjustable by on-board buttons.

Specifications: • Output power (x 2 channels): 0.5W x 2 @ 8 ohms (<0.19% THD+N), 1.5W x 2 @ 8 ohms (<10% THD+N), 1W x 2 @ 4 ohms (<0.17% THD+N), 2.6W x 2 @ 4 ohms (<10.0% THD+N) • Frequency response: 20 Hz to 20 kHz (±3 dB) • Signal to noise ratio: 85 dB (22 Hz to 22 kHz, THD = 1% • Power supply range: 2.5V to 12V • 2.1 mm DC input jack • Dimensions (mm): 74.4 L x 54.8 W x 18 H.
