AZ386

General Description

The AZ386 is a power amplifier designed for use in

low voltage consumer applications. The gain is inter-

nally 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 opera-

ting from a 5V supply, making the AZ386 ideal for

battery operation.

This IC is available in SOIC-8 and DIP-8 packages.
