LM386N-4, 8 Pin, Audio Power Low Voltage Amplifier 700mW.
The gain of this IC is internally set to 20 to keep external part count low, but adding an external resistor and capacitor between pins 1 and 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 6 volt supply, making the LM386 ideal for battery operation.
Features:
- Minimum external parts
- Supply voltage range: 5V-18V
- Low quiescent current drain: 4mA
- Voltage gains from 20 to 200
- Ground referenced input.
- Self-centering output quiescent voltage
- 8-pin DIP package
