Data Sheet
LOW VOLTAGE AUDIO POWER AMPLIFIER
General Description
The AZ386 is a power amplifier designed for use in
low voltage consumer applications. The gain is internally set to 20 to keep external part count low, but the
addition of an external resistor and capacitor between
pin 1 and pin 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 24mW when operating from a 5V supply, making the AZ386 ideal for
battery operation.
This IC is available in SOIC-8 and DIP-8 packages.
