lm386 smd earphone power ?
Hello,
I want to amplify 2 guitar pickups with a lm386 so I could hear them in a regular (smartphone like) earphone
I dug a bit and it seems a single coil guitar pickup is around 50–100 mV output (doubled since I use humbuckers)
let's say, max 400 mV since I use 2 humbuckers
I have some smd 386 amp
I think they are .25W (cant find the info anywhere, but I read it a while ago)
are they powerfull enough ?
circuit I found (probably drawn straight from datasheet) : https://www.gadgetronicx.com/headphone-amplifier-circuit/
regards
