I've been playing around with the LM386 with an electret mic as input and an earbud as the output but it clips/distorts way before it can get any real volume. Is there a better audio amplifier for headphones/earbuds?
without a schematic, i can throw out some details...
12V bias
INPUT:
2.2k to the electret
1uF dc blocking cap
40k log pot w/13k in parallel to get no more than around 10k across it
OUTPUT
10 Ohm and .056uF in series to ground from LM386 output
560uF cap to earbud
LM386 decoupled with 0.15uF ceramic
