The Two-Channel Instrumentation Amplifier Based on a New Radiation-Hardened Microcircuit MH2XA010–03 for Reading Signals of Differential Piezoelectric Converters

摘要

The signal readout channel of differential piezoelectric transducers based on the semicustom integrated circuit (IC) MH2XA010-03 is studied. The developed electrical circuit is presented and the results of measurements of the main parameters of the IC, oriented to the use in acoustic systems of measuring the temperature of the gas stream of reactive engines are presented. This measuring system includes two jet-acoustic sensors, piezoelectric converters, low-pass filters and a two-channel instrumentation amplifier made on the elements of the MH2XA010-03 chip.
