Abstract
Disclosed is a differential amplifier having a pair of input terminals and multiple output terminals. Various ones of the output terminals are selectively enabled in response to output selection signals. Within the amplifier is a first transistorized circuit which generates analog signals representative of any voltage difference between the input terminals. A second transistorized circuit within the amplifier couples these analog signals to selected ones of the output terminals in response to the output selection signals.
