Data Sheet AZ386 LOW VOLTAGE AUDIO POWER AMPLIFIER General Description Features 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. Wide Supply Voltage Range: 4V to 16V Low Quiescent Current Drain: 6mA Voltage Gains from 20 to 200 Battery Operation Minimum External Parts Low Power Dissipation Low Distortion Applications · · · · · · · · · This IC is available in SOIC-8 and DIP-8 packages.

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 may affect device reliability. Note 2: 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.
