LM386 Low Voltage Audio Power Amplifiers

Texas Instruments offers the LM386 wide VIN low power audio amplifiers with internal gain

Image of Texas Instruments' LM386 Low Voltage Audio Power AmplifiersTexas Instruments' LM386 are power amplifiers 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 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 24 mW when operating from a 6 V supply, making the LM386 ideal for battery operation.
