This two-stage operational amplifier has an LM358 chip as its core. It can amplify weak AC signals such as sine wave signals or positive and negative pulse signals. It can also amplify millivolt signals.
There are two potentiometers. They set the magnification of the first and second stage respectively. The total magnification is the product (multiplication) of the magnification of the two stages. The magnification is therefore adjusted on a large scale. (If the first stage is magnified 20 times and the second stage is magnified 100 times, the total magnification is 2000 times)
Specification:
- Chip: LM358
- Product type: Voltage amplifier
- Operating voltage: Positive and negative DC 2-14 V
- Current output: Maximum 15-20 mA (non-linear)

Calculation:
-
Voltage output: Output = Input voltage signal * Gain
- Magnification: Multiple = First multiple x second multiple.
