This is the LM380 Audio Power Amplifier Kit with PCB.It includes the very popular LM380 Audio Power Amplifier 8-Pin IC rated at 2.5 Watts, a well-designed PCB for the LM380, schematics, and the parts to build it. This is probably the world's most popular Audio Power Amplifier Integrated Circuit ever made.
The gain is internally fixed at 34 dB. A unique input stage allows ground referenced input signals. The output automatically self-centers to one-half the supply voltage. The Output Power is rated for 2.5 Watts with a THD of 0.2%.

Uses include MP3 output amplifiers, guitar amplifiers, simple phonograph amplifiers, intercoms, line drivers, teaching machine outputs, alarms, ultrasonic drivers, TV sound systems, AM-FM radio, small servo drivers, power converters, etc.

This kit is also offerd with a "Built & Tested" option for those that do not want to build the kit themselves.

The PCB is 1.4" long x 2.30" wide made of .062" FR-4 epoxy glass. All holes are plated through. The traces are wide to withstand numerous circuit changes.
This kit does not include the tools you will need to assemble the circuit. You will need tools such as a soldering iron, solder, wire cutters, etc.

Below is a detailed introduction to component identification and kit assembly.
