PJ386

m o .c U 4 t designed for use in low PJ386 is a power amplifier e T he voltage consumer applications. The gain is internally set e h to 20 to keep external part count low, but the addition of an external resistor andS capacitor between pins 1 and 8 will a increase the gain to at any value up to 200. .D FEATURES w Battery operation w wMinimum external parts Wide supply voltage range 4-12 Volt Low quiescent current drain 4mA Voltage gains from 20 to 200 Ground referenced input self-centering output quiescent voltage Low distortion Eight pin dual-in-line package PJ386 Low Voltage Audio Power Amplifier The inputs are ground referenced while the output is automatically biased to one half the supply voltage.The quiescent power drain is only 24 milliwatts when operating from a 6 volt supply,making the PJ386 ideal for battery operation.
