Hiya,
I seek a mono 1W to 1.5W (power iC amp) with no capacitors whatsoever in the signal path (DC coupled?).
The power supply will be 5V-7V
My preamp is an opamp and already biased at 1/2 VCC, the input to the preamp will be a coil pickup.
I'm figuring if I connect one leg of the input pickup coil to 1/2 VCC & the other to the first opamp stage input pin , then that that bit (the input) is therefore covered off (ie no caps needed) - but most IC audio amps 'example circuits' have decoupling caps at their input pin ...if my preamp circuit is already operating at 1/2 VCC....I'm assuming I can simply ignore those caps?
This is exploratory territoy for me, so general advice warmly received along with an tips for suitable IC amp contenders!
