ABSTRACT:
Disclosed is an analog multiplexer in which a plurality of emitter follower differential amplifiers formed of several pairs of bipolar transistors connected in parallel with each other are connected in common to one terminal of a power source through a current mirror load circuit, and to the other terminal of the power source via a switch circuit and a constant-current source. The switch circuit is to connect the constant-current source selectively to the common conjunction of the emitters of each pair of emitter follower differential amplifiers.
