LM386 Low Voltage Audio Power Amplifier General Description The LM386 is a power amplifier designed for use in low volt- age 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 auto- matically biased to one half the supply voltage. The quies- cent power drain is only 24 milliwatts when operating from a 6 volt supply, making the LM386 ideal for battery operation. Features n Battery operation n Minimum external parts n Wide supply voltage range: 4V–12V or 5V–18V n Low quiescent current drain: 4 mA n Voltage gains from 20 to 200 n Ground referenced input n Self-centering output quiescent voltage n Low distortion n Available in 8 pin MSOP package Applications n AM-FM radio amplifiers n Portable tape player amplifiers n Intercoms n TV sound systems n Line drivers n Ultrasonic drivers n Small servo drivers n Power converters Equivalent Schematic and Connection Diagrams DS006976-1 Small Outline, Molded Mini Small Outline, and Dual-In-Line Packages DS006976-2 Top View Order Number LM386M-1, LM386MM-1, LM386N-1, LM386N-3 or LM386N-4 See NS Package Number M08A, MUA08A or N08E January 2000 © 2000 National Semiconductor Corporation DS006976 www.national.com |
