Abstract
A method of expanding the operating range of the amplifier is presented, which allows reducing the coefficient of nonlinear distortions of the calibration signal to 0.003%. The structural diagram of the analog-digital amplifier of the input signal to the output, which provides minimal nonlinear distortion of the output signal, is given. The principle of operation of the amplifier is described. The input scaling amplifier and output highvolt digital-to-analog converter transmission coefficients dependens diagrams on the input signal amplitude are given. The results of experimental studies of the metrological characteristics of the experimental sample of the amplifier are given. References 10, figures 2.
