资 源 简 介

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 up to 200.   The inputs are ground referenced while the output is automaTIcally biased 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.
