LM386N LM386 audio power amplifier IC chip DIP-8DescriptionThe LM386M-1 and LM386MX-1 are power amplifiersdesigned for use in low voltage consumerapplications. The gain is internally set to 20 to keepexternal part count low, but the addition of an externalresistor and capacitor between pins 1 and 8 willincrease the gain to any value from 20 to 200.The inputs are ground referenced while the outputautomatically biases to one-half the supply voltage.The quiescent power drain is only 24 mW whenoperating from a 6-V supply, making the LM386M-1and LM386MX-1 ideal for battery operation.Features1• Battery Operation• Minimum External Parts• Wide Supply Voltage Range: 4 V–12 V or5 V–18 V• Low Quiescent Current Drain: 4 mA• Voltage Gains from 20 to 200• Ground-Referenced Input• Self-Centering Output Quiescent Voltage• Low Distortion: 0.2% (AV = 20, VS = 6 V, RL = 8 O,PO = 125 mW, f = 1 kHz)• Available in 8-Pin MSOP Package Applications• AM-FM Radio Amplifiers• Portable Tape Player Amplifiers• Intercoms• TV Sound Systems• Line Drivers• Ultrasonic Drivers• Small Servo Drivers• Power Converters . .
