LOW VOLTAGE AUDIO POWER
AMPLIFIER
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.
