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.
