0.1 ohm resistors are used because the gain of each LM3886 is determined by 1% resistors, and the power in a higher value resistor would be high, requiring them to be big and expensive.joecool85 said:Hmm. When paralleling lm3886s, which are way larger, 50w a piece, you use 0.1 ohm resistors.
The LM386 uses a 0.05uF cap in series with a 10 ohm resistor to ground as an output load to prevent it from oscillating when the inductance of a speaker load results in a high impedance at high frequencies.Do I need the part with the 2.7 ohm resistors/cap to ground?
The gain of the higher power amps is determined by accurate 1% resistors. Therefore their gains will be closer so smaller value and size resistors can be used.joecool85 said:Ok, so higher powered paralleling requires smaller ohm resistors then?
