Product Description
The LM386 is a power amplifier specifically engineered for low voltage consumer applications. Its internal gain is pre-set to 20 to minimize external component requirements. However, by incorporating an external resistor and capacitor between pins 1 and 8, the gain can be adjusted to any value between 20 and 200.
The inputs are ground referenced, and the output automatically biases to half the supply voltage. With a quiescent power drain of only 24 mW when powered by a 6-V supply, the LM386 is exceptionally well-suited for battery-operated devices.
