Powered stereo version of the popular LM3886 based audio amplifier, the module contains on-board SMPS and two LM3886 Amplifier IC’s. Output power is 2x60W on 4R load and up to 2x40W on a 8R load with THD below 0.01%. It uses DC servo and doesn’t use any coupling capacitor on the signal path (although there is provision for input capacitor on the board but not used) adding no coloration to the sound. The frequency response extends virtually from DC to over 40KHz with better than 3dB linearity and better than 1dB linearity up to 22KHz. It also includes DC speaker protection, which will shut-down the power supply in case that DC component is detected on the amplifier output. It has turn On/Off click/pop noise free. The heatsink is not included but a better than 0.6*/W heatsink must be used for reliable operation. LM3886TF plastic case is used for easier installation.
Mains voltage 230V default, 110V selectable from a jumper. Overall board size is 100x100mm and up to 36mm tall from the board base, suitable to be mounted in low-profile enclosures.
