Overview
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 automatically 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 Ordering Information PART NO.
