LM389 Low Voltage Audio Power Amplifier

with NPN Transistor Array

Low quiescent current drain

General Description

The LM389 is an array of three NPN transistors on the same

substrate with an audio power amplifier similar to the

LM386.

Voltage gains from 20 to 200

Ground referenced input

Self-centering output quiescent voltage

Low distortion

The amplifier inputs are ground referenced while the output

is automatically biased to one half the supply voltage. The

gain is internally set at 20 to minimize external parts, but the

addition of an external resistor and capacitor between pins

4 and 12 will increase the gain to any value up to 200.

Transistors

Operation from 1 mA to 25 mA

Frequency range from DC to 100 MHz

Excellent matching

The three transistors have high gain and excellent matching

characteristics. They are well suited to a wide variety of ap-

plications in DC through VHF systems.

Applications

AM-FM radios

Portable tape recorders
