Low Voltage Audio Power Amplifier (LM386)

The LM386 and 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 from 20 to 200.

Features:
• Battery Operation
• Minimum External Parts
• Wide Supply Voltage Range: 4 V–12 V or 5 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 Ω, 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
