LM386, Low Voltage 1W Audio Power Amplifier.
Manufactured by: National Semiconductors.
Comes in a pack of 5 ICs.
LM386 N1 General Description
The LM386 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. The inputs are ground referenced while the output
automatically biases to one-half the supply voltage. The quiescent
power drain is only 24 milliwatts when operating from a 6 volt supply,
making the LM386 ideal for battery operation.
