Abstract:

The temperature stability of the instrumental and two-stage amplifiers based on the operational amplifier LM358 (STMicroelectronics) amplifiers is experimentally studied. The purpose of this study is to develop an evaluation criterion for measuring the sensitivity of measuring circuits to temperature changes, perform comparative tests and determine the preferred options for circuitry solutions. The purpose of this study is to develop the experimental procedure, the structure and components of the experimental setup, perform comparative tests of various amplifier circuits in the temperature range 20 ℃ -60 ℃.
