ABSTRACT:
A differential amplifier circuit has a differential amplifier circuit section for amplifying a difference voltage between an inverting input node and a non-inverting input node, and an output buffer circuit for outputting, to an output node, the amplified difference. The differential amplifier circuit section is connected to a first high potential power supply node and a first low potential power supply node, and is driven by potentials applied to the first high potential and first low potential power supply nodes. The output buffer circuit is connected to a second high potential power supply node and a second low potential power supply node, and is driven by potentials applied to the second high potential and low potential power supply nodes.
