Brief NPN PNP BJT push pull amplifier circuit fragment

Table of Contents

Combining NPN and PNP BJT emitter followers creates a push pull amplifier that transfers the voltage of a signal minus the B-E diode drop of the particular transistor to a load regardless of whether it is more positive or negative than the 0V reference point ground on the other side of the load.

I used a TLE2426 to split the rail (turn a 10V supply into a ±5V in relationship to 0V ground). Brief TLE 2426 three terminal rail splitter virtual ground component introduction . A op amp can also be used to do the same thing Brief op amp rail splitter circuit turning single into split dual supply
