Abstract: PURPOSE:To obtain an insulation type current amplifier which outputs a large output and is manufactured in simple constitution by providing a differential amplifier, current control element, switching means, and feedback control. CONSTITUTION:A signal S1 when outputted by a D/A converter 4 is voltage- amplified by the differential amplifier 13 and current-amplified by the current control element 14 to obtain a signal S2. Therefore, the waveform of the signal S2 is equal to that of the signal S1. The S2 flows through the center tap of the primary winding of a transistors (TR) 15 and 16, and feedback means in order when a TR16 is on or through the center tap of the primary winding, a TR17, and the feedback means 18 in order when the TR17 is on. When currents flowing in the collectors of the TRs 16 and 17 are signals S3 and S4, the S3 and S4 are signals which alternate a section of the same waveform with the S2 and a section of level 0. Consequently, the waveform obtained by the full-wave rectification 25 of the secondary-side output of the TR15, i.e. the waveform of the voltage across a load resistance Rl is the same with the signal S1.
