What could be a near rail-to-rail opamp with very low voltage for this use? LM386 seems to be out of limits for my needs.
How do I choose it from datasheets? What values are important (of course limits & power) but what else? Is there something more important than power inputs & current limits?
on this schematic I did not calculate component values yet.
I want to make a very light and portable mic amplifier on 2 batteries. It should consume very low power and have medium/high amplification.
What could be a near rail to rail amp with very low voltage for this use?
I tried from this datasheet to guess that the LT1494 would fit this need. Is this correct? (If not, why?) LT1494 datasheet
For audio, will 100nF be ok for C1 & C2?
mic will be an electret connected device may be another amplifier or why not a speaker
