(K115)

Uses 2 LM386N-1 for a stereo amplifier. Ideal for walkman and other battery powered items. 4V - 12V DC. Instructions PCB and components supplied.

This is a 1 watt per channel, stereo amplifier module Kit using two LM386N IC’s from National Semiconductor. It is basically two of our CPS17’s on a single PC board, with a dual gang pot. It will operate best from 6-12V DC and will work well from a battery since the quiescent current drain is only 10 mA. It requires no heat sinks for normal use. The input and output are both ground referenced. Maximum output will be obtained with a 12V power supply and 8 ohm speaker, however it is particularly suitable for driving headphones from a supply as low as 4V. Speakers are not supplied. They should be rated at 3W or over. PCB size 63mm x 40mm (2.5" x 1.5"). (CPS115)

2W amplifier module LM380

This is a very simple amplifier built around the LM380 IC. It can deliver up to 2W into an 8 ohm speaker depending on the supply voltage. Instead of using a heatsink or heat fins the heat produced is dissipated through the center pins of the IC into the copper overlay left on the PCB. If you do require a sustained output of more than ½ watt, you will need to add a heatsink (not included). The IC solders directly to the PCB.
PCB size: 1.75in x 1.75in (45mm x 45mm)

Power output:
> 2 Watt max. (4-8 ohms, 20V)
> 1 Watt max. (4-8 ohms, 12V)
