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 LM386 ideal for battery operation.

Features

• Battery operation

• Minimum external parts

• Wide supply voltage range: 4V–12V or 5V–18V

• Low quiescent current drain: 4mA

• Voltage gains from 20 to 200

• Ground referenced input

• Self-centering output quiescent voltage

• Low distortion: 0.2% (AV = 20, VS = 6V, RL = 8Ω, PO = 125mW, f = 1kHz)
