Part Description: LM386 Low Voltage Audio Power Amplifier


Part Details:

LM386 August 2000 Low LM386 V Low Voltage Audio Power Amplifier oltage General Description Features The LM386 is a power amplifier designed for use in low volt- n Battery operation age consumer applications. The gain is internally set to 20 to n Minimum external parts Audio keep external part count low, but the addition of an external n Wide supply voltage range: 4V­12V or 5V­18V resistor and capacitor between pins 1 and 8 will increase the n Low quiescent current drain: 4mA gain to any value from 20 to 200. n Voltage gains from 20 to 200 The inputs are ground referenced while the output automati- n Ground referenced input Power cally biases to one-half the supply voltage. The quiescent n Self-centering output quiescent voltage power drain is only 24 milliwatts when operating from a 6 volt n Low distortion: 0.2% (A = 20, V = 6V, R = 8, P = supply, making the LM386 ideal for battery operation. V S L O 125mW, f = 1kHz) n Available in 8 pin MSOP package Amplifier Applicationsn 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 Small Outline, Molded Mini Small Outline,and Dual-In-Line Packages DS006976-2 Top View Order Number LM386M-1, DS006976-1 LM386MM-1, LM386N-1, LM386N-3 or LM386N-4 See NS Package Number M08A, MUA08A or N08E
