Abstract :
Describes a monolithic 70 V IC which is an integral part of a PCM subscriber line interface circuit (SLIC). A special design allows the realization of a line driving operational amplifier with stringent requirements on power drive, consumption, output overload protection and breakdown voltage. Other special SLIC functions are also implemented. Experimental results demonstrate the performance of the chip.
