Patent ID: 6933753

Claim:
A sensor signal output circuit comprising: a first differential amplifier including an input end connected to a first reference voltage setting part, and an other input end to which a signal is input; a first load resistor for the first differential amplifier; a first transistor including a gate connected to an output end of the first differential amplifier, and a source connected to a first constant current source; a second transistor including a gate connected to a point of connection between the first constant current source and the first transistor, and a drain connected to a second constant current source; an output terminal connected to the drain of the second transistor; and a limiter section, the limiter section including at least: a second differential amplifier including an input end coupled to the output terminal, and an other input end coupled to a second reference voltage setting part; a second load resistor for the second differential amplifier; and a third transistor including a gate connected to an output end of the second differential amplifier, and a source connected to the gate of the second transistor.
