LM386 amplifier equivalent, low voltage audio power amplifier.
*Battery Operation *Minimum External Parts *Wide Supply Voltage Range: 4V~12V *Low Quiescent Current Drain:4mA *Voltage Gains: 20~200 *Ground Referenced Input *Self-Cente.
The gain is internally set to 20 to keep external part count low, but the addition of an external resistor and capacito.
