Source: InternetPublisher:酷到被通缉 Keywords: Amplifier Updated: 2024/09/09
The measurement amplifier circuit composed of OP07 is shown in the figure below.
In order to improve the power supply impedance of the integrated operational amplifier, a 2.2μF ceramic chip capacitor for bypass is connected to the ground at the positive and negative power supply terminals of each integrated operational amplifier; in order to achieve 1N1000 times adjustable gain and precise adjustment, the gain adjustment resistor is composed of three adjustable resistors with different resistance values connected in series.
