NOT RECOMMENDED FOR NEW DESIGN USE PAM8304 AZ386 LOW VOLTAGE AUDIO POWER AMPLIFIER Description Pin Assignments The AZ386 is a power amplifier designed for use in low voltage consumer applications. The gain is internally set to 20 to keep (Top View) (Top View) 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 GAIN 1 8 GAIN GAIN 1 8 GAIN from 20 to 200. INPUT- 2 7 BYPASS 2 7 BYPASS INPUT- 6 V INPUT+ 3 CC INPUT+ 3 6 V CC The inputs are ground referenced while the output automatically V GND 4 5 OUT biases to one-half the supply voltage. The quiescent power drain is GND 4 5 V OUT only 24mW when opera-ting from a 5V supply, making the AZ386 ideal for battery operation. SOIC-8 DIP-8 This IC is available in SOIC-8 and DIP-8 packages.
