Filed: 1990-09-18
Abstract: PURPOSE:To make small the leak current which causes input error by connecting the anode of a diode to the side of the noninversion input terminal of an operating amplifier, where a measured signal is added to the noninversion input terminal, and connecting a voltage follower, where the voltage of the inversion input terminal of the operating amplifier or + power is added, to the cathode. CONSTITUTION:FETs 17 and 21 function as voltage followers. In the measurement mode M, the voltage VIN inputted in an input terminal 1 is added to the noninversion input terminal lo fan operating amplifier 4. Hereupon, imaginary short is established between the noninversion input terminal and the inversion input end, and the potential of the noninversion input terminal becomes VIN, and is added to the FETs 17 and 21. Defining the gate source voltage of these FETs 17 and 21 as VGS, the potential of the point D becomes (VIN +VGS). Accordingly, the potential difference between the points D and E becomes only the VGS, and the leak current becomes smaller than conventional one. Hereby, an input/output protective circuit with small leak currents can be gotten.
