AZ386
LOW VOLTAGE AUDIO POWER AMPLIFIER
Description
The AZ386 is a power amplifier designed for use in
consumer applications. The gain is internally set to
external part count low, but the addition of an external
capacitor between pin 1 and pin 8 will increase the gain
from 20 to 200.
Pin Assignments
low voltage
20 to keep
resistor and
to any value
The inputs are ground referenced while the output automatically
biases to one-half the supply voltage. The quiescent power drain is
only 24mW when opera-ting from a 5V supply, making the AZ386
ideal for battery operation.

2. Stresses greater than those listed under Absolute Maximum Ratings can cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied.
Exposure to Absolute Maximum Ratings for extended periods can affect device reliability.
3. For operation in ambient temperatures (TA) above +25oC, the device must be derated based on a +150oC maximum junction temperature and 1) a
thermal resistance of 107oC/W junction to ambient for the Dual-in-Line package and 2) a thermal resistance of 172oC/W for the small outline package.
