Low Voltage Audio Power Amplifier LM386N/D
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 D386 ideal for battery operation.
