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 3):
A differential amplifier circuit according to  claim 1 :\n wherein the first differential input pair is formed of PMOS depletion transistors, the second differential input pair is formed of PMOS enhancement transistors, and the switch is formed of a PMOS 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.
