General Description

The LM386M-1 and LM386MX-1 are power amplifiers designed for use in low voltage consumer applications.

The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacitor between pins 1 and 8 increases the gain to any value from 20 to 200.

The inputs are ground referenced while the output automatically biases to one-half the supply voltage.
