2 Watt Stereo (2 Channel) Audio Amplifier
This is actually two CK700's - 1 watt amplifier modules on a single PC board with 2 volume controls. This will allow you to independently control the left and right side of a stereo signal, or two separate mono inputs. It uses two LM386N ICs from National Semiconductor.
It will operate best from 6-12V DC and will work well from a battery since the quiescent current drain is only 10 mA, if the LED is not used. It requires no heat sink 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.
