LOW VOLTAGE AUDIO POWER
AMPLIFIER
DESCRIPTION
The UTC386 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
*Battery operation
*Minimum external parts
*Wide supply voltage range:4V~12V
*Low quiescent current drain(4mA)
*Voltage gains:20~200
*Ground referenced input
*Self -centering output quiescent voltage
*low distortion
