    • Output signal waveform having high input signal reproducibility is outputted from inductive load or the like. Output signals V1a and V1b obtained by feeding back an output signal Vp-n1 at output terminals 50 and 51 across load L1 to input terminals 9a and 9b are compared with an input signal Vin to detect an error between signals; a first error suppression signal Vout1 is produced such that the detected error between the signals is suppressed; inclination of first error suppression signal Vout1 is detected, and a second error suppression signal Vout2 is produced such that inclination error to input signal Vin is suppressed based on the detected inclination signal; and the ratio between the period that electric power is supplied to the load L1 and the period that electric power is not supplied to the load L1 is modified according to the error of the error suppression signal.
