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 1):
A differential amplifier circuit, comprising:\n an inverting input terminal; a non-inverting input terminal; an output terminal; a first differential input pair configured to receive input from the inverting input terminal and the non-inverting input terminal; a second differential input pair configured to receive input from the inverting input terminal and the non-inverting input terminal, the second differential input pair including transistors that have a threshold value different from a threshold value of transistors included in the first differential input pair; a current source configured to supply current to the second differential input pair; and a switch provided between the first differential input pair and the current source, and is configured to be turned on and off in accordance with a voltage across the inverting input terminal and the non-inverting input terminal.
