LM386-1
Low Voltage
Audio Power Amplifier
Low Voltage Audio Power Amplifier
General Description
Features
The LM386-1 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
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.
The inputs are ground referenced while the output automati-
cally biases to one-half the supply voltage. The quiescent
power drain is only 24 milliwatts when operating from a 6 volt
supply, making the WS386M-1 ideal for battery operation
n Wide supply voltage range: 4V–12V
n Low quiescent current drain: 4mA
n Voltage gains from 20 to 200
n Ground referenced input
n Self-centering output quiescent voltage
n Low distortion: 0.2% (AV = 20, VS = 6V, RL = 8Ω, PO =
125mW, f = 1kHz)
n Available in 8 pin SOP package and DIP 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
