ryanleung Posted March 7, 2006 Report Share Posted March 7, 2006 My project is infrared headphone. I would like to supply 9V for my circuit but I do not like to use 9V battery (1.5Vx6). Any suggestion about it.Thx~~~ Quote Link to comment Share on other sites More sharing options...
audioguru Posted March 7, 2006 Report Share Posted March 7, 2006 You didn't post your project's schematic so we can't see what supply voltage its parts need.Will the parts work from the 2.0V to 3.0V from a couple of battery cells? Quote Link to comment Share on other sites More sharing options...
Tony_Stoynov Posted March 7, 2006 Report Share Posted March 7, 2006 Hi,You can use just one bateries, a 9 V cells, or a 3 LiOn cells, this will give you around 11 V, depent from the current that you will be need have a different possibilities, if can give me us more specific parameters, specially current, we can give you the best decision. p.s. why you use 9 V, why not use a 3 or 5 V schem?
