audio LM386 with Gain of 40 Electrical Engineering ... 4 Answers. The answer for a gain of 40 should give Rp = 600 Ohms (1350 Ohms in parallel with the appropriate resistor), giving an answer of about 1250 Ohms for the resistor needed to set the gain. Oddly, using this formula with the value given in the datasheet for a gain of 50 (1.2 kOhms) only gives a gain of 38.2.
