LED Convertible Bar Graph Kit


Part Number: ph-80-165

Typically used to indicate sound levels in playback equipment, may be used in other applications such as a meter in a receiver, level indicator in field strength meter etc. This circuit is set up to show both a left and right channel output in a series of eight LEDís per side. Channels are independent of one another. By "convertible", we mean that you could use this circuit with just one input and all sixteen LED can be used to indicate relative level. Input level is user adjustable; sensitivity can be set all of the way from millivolts to a few volts per step (LED). Very, very linear indication. The kit may be operated on 5 to 18 volts DC.
