LM358 is the core secondary computing amplifier, which can magnify DC signals, such as DC voltage signals, DC veins signals, which can be enlarged by the millival or even weaker signals.The second level is adjusted by a single -level amplification multiple, but the total amplification multiple is the product of the two -level multiple, so the amplification multiple will be adjusted to a large

(If the first level is adjusted to 20 times, then if the second level is adjusted to 100 times, then the total amplification multiple is 2000 times)

Note: If your friends take a large number of large folds that do not tell the requirements, we will ship according to the default 1-1000 times

Plate parameters:

1. Power supply voltage: 3.5-24V DC power supply

2. current output: large 15-20mA (non-linear)

3. Voltage output: output = input voltage signal*magnifying multiple

4. magnifying multiple: Total multiple = first level multiple*second level multiple

5. Board size: 45.3mm wide 16.2mm

6. The two potentiometers on the board rotate the clockwise rotation counterclockwise.
