Abstract
To provide a current detection circuit capable of suppressing the occurrence of a large potential difference between input terminals of a differential amplifier circuit, and preventing degradation of input transistors. A differential amplifier circuit is equipped with a clamp circuit which limits gate-source voltages of a pair of PMOS transistors each having a bulk and a source connected to each other with the sources of the pair of PMOS transistors as input terminals.
