Claims

[Scope of utility model registration request]

A linearizer that converts an input signal from analog to digital and then inputs it into a microprocessor and performs linearization includes a digital-to-analog converter, an amplifier that subtracts an offset from the applied input signal and amplifies it, and a a sampling circuit that supplies a voltage corresponding to the offset; a comparator to which an output signal of the amplifier is applied to one input terminal; and a first changeover switch that selectively supplies a plurality of input signals to the amplifier. , a second changeover switch that selectively connects the digital-to-analog converter to the sampling circuit and the comparator, and the connection state of the first and second changeover switches, the amplification degree of the amplifier, and the digital/analog converter;
A linearizer comprising a microprocessor that controls a digital value set in an analog converter, converts an input signal from analog to digital, takes it in, and linearizes the input signal.
