Small mono amplifier is surprisingly powerful for its size, and efficient - able to deliver up to 2.5 Watts into 4-8 ohm impedance speakers.
Features a volume trim pot so you can set/adjust the amount of amplification on the board.
* Output Power: 2.5W at 4Ω, 10% THD, 1.5W at 8Ω, 10% THD, with 5.5V Supply * 50dB PSRR at 1KHz * Filterless design, with ferrite bead + capacitors on output. * Fixed 24dB gain, onboard trim potentiometer for adjusting input volume. * Thermal and short-circuit/over-current protection * Low current draw: 4mA quiescent and 1uA in shutdown mode
