UTCLM386 LINEAR INTEGRATED CIRCUIT

LOW VOLTAGE AUDIO POWER

AMPLIFIER

DESCRIPTION

The UTC LM386 is a power amplifier, designed for

use in low voltage consumer applications. The gain is

internally set to 20 keep the external part count low,

but the additional of external resistor and capacitor

between pin 1 and pin 8 will increase the gain to any

value up to 200.

FEATURES

*Minimum external parts

*Wide supply voltage range:

*Voltage gains:20~200

*Ground referenced input

*Low distortion

4V~12V
