I would like to ask how I should connect the input electrolytic capacitor to LM3886 IC. Searching online did not result in any finds whatsoever. Only one schematic had a properly marked input capacitor. Since an electrolytic capacitor is polarised, I would like to know how this should be connected to the input. The IC's non-inverting input is connected to a resistor chain of two series resistors. The resistor that directly connects to the chip is 1k and the other , 22k, connects to ground. Signals will be fed at the point between these resistors. Which capacitor's electrode should be connected to this point? The input signal will be applied between the capacitor's other terminal and ground.
