description | To provide a single differential conversion circuit capable of having a wide output operation range.SOLUTION: A single differential conversion circuit 10 includes a first level shifter 12 that shifts the level of an input signal IN and a second output signal OUT2 to generate a first level shift signal INM and a second level shift signal INP, a differential amplifier 13 that generates a first amplification signal AOP1 obtained by amplifying a difference between the first level shift signal and the second level shift signal upon the input of the first and second level shift signals, and a second amplification signal AOP2 with the inverted phase, and a second level shifter 14 that shifts the level of the first amplification signal and the second amplification signal to generate a first output signal and the second output signal and supplies the second output signal to the first level shifter. The differential amplifier includes a differential transistor pair including transistors of a first conductivity type. The first level shifter includes a transistor pair of a second conductivity type, and the second level shifter includes the transistor pair of the first conductivity type.SELECTED DRAWING: Figure 1
