LM386 Specs Features and Application – Audio Power Amplifier

Thursday, 12. March 2009 by Arya
When using the LM386 with higher gains (bypassing the 1.35 kW resistor between pins 1 and 8) it is necessary to bypass the unused input, preventing degradation of gain and possible instabilities. This is done with a 0.1 ?F capacitor or a short to ground depending on the dc source resistance on the driven input.
