LM386 Low Voltage Audio Power Amplifier

The LM386M-1 and LM386MX-1 are power amplifiers 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.

Specifications :

• Wide Supply Voltage Range: 4V to 18V
• Low Quiescent Current Drain: 4 mA
• Voltage Gains from 20 to 200

Features :

• Battery Operation
• Minimum External Parts
• Ground-Referenced Input
• Self-Centering Output Quiescent Voltage
• Low Distortion: 0.2% (AV = 20, VS = 6 V, RL = 8 Ω,
• PO = 125 mW, f = 1 kHz)

Applications :

• AM-FM Radio Amplifiers
• Portable Tape Player Amplifiers
• Intercoms
• TV Sound Systems
• Line Drivers
• Ultrasonic Drivers
• Small Servo Drivers
• Power Converters
