The LM386L is a power amplifier 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 will increase the gain to any value from 20 to 200.
Supply Voltage: 4-12V
Quiescent Current: 4-8mA
Output Power: 325 mW--VS= 6V, RL=8 Ohm, THD = 10%
Voltage Gain: 26-46 dB
Input Resistance: 50K Ohm
