Abstract:
To perform a rail-to-rail input operation, provided is a differential amplifier circuit including a first differential input pair and a second differential input pair which has a threshold value different from that of the first differential input pair. Both the differential input pairs do not operate at the same time. A transistor is connected between the first differential input pair and a current source to achieve a configuration in which the first differential input pair and the second differential input pair do not operate at the same time.

Claim (Index 2):
A differential amplifier circuit according to  claim 1 :\n wherein the first differential input pair is formed of NMOS depletion transistors, the second differential input pair is formed of NMOS enhancement transistors, and the switch is formed of an NMOS enhancement transistor; and wherein the switch is configured to be turned on and off in accordance with the voltage across the inverting input terminal and the non-inverting input terminal to supply current to one of the first differential input pair and the second differential input pair.
