A Monolithic Power Driver for Complementary Power Transistors

A Monolithic Power Driver has been designed to drive a pair of complementary output transistors. This prime function is as an audio amplifier for outputs up to 70 W rms. It features low standby current l4mA typical; high output current capability, 120 mA; low bias current; 1.5 uA typical; internal current limiting; external current and power limiting; adjustable quiescent current in the output transistors with temperature compensation; wide power bandwidth 100 kHz; wide power supply operating range, 10-50V and excellent linearity.
