„ DESCRIPTION
The UTC 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 pin 1 and pin 8 will increase the gain to any value up
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 voltage supply, making
the LM386 ideal for battery operation.
