A PRECISION LOW-FREQUENCY ANALOG-TO-DIGITAL CONVERTER FOR ADVANCED SYSTEMS OF TECHNICAL DIAGNOSTICS AND NONDESTRUCTIVE TESTING

The main results of the development of a precision low-current meter based on a nonlinear ADC are presented. It is shown that the application of the method of nonlinear analog-to-digital conversion and a controlled voltage level at the non-inverting input of an integrating operational amplifier allows both high sensitivity and a wide dynamic range with a small spread of output codes. The use of the laboratory sample of the meter for cyclic tensile testing of steel specimens is described.

Keywords: nonlinear analog-to-digital converter, nanoampere current meter, integrating operational amplifier, magnetostriction measurement
