Product description: Audio amplifier NJM2073D 2 V - 15 V 1 W
A set to build a two-channel audio amplifier based on theNJM2073D chip, which allows you to connect a speaker of up to 1 W per channel. The kit includes two 8 ohm0.5 Wspeakers, a clipfor 9 V batteries,a 3.5 mm jack cable and smallelectronic components necessary to build the amplifier. The assembly of the set requires soldering of the elements threaded onto the PCB. The whole can be poweredfrom 2 V to 15 V DCbut at low voltage the maximum volume level will be significantly reduced. The board has dimensions of 58 x 35 mm.
