LM358 Weak Signal Amplifier Voltage Amplifier Secry Operational Amplifier Module Single Power Signal Collector

Module parameters: LM358 is the core two-stage operational amplifier, which can amplify DC weak signals, such as DC voltage signals, DC pulse signals, can amplify signals of millivolts or even weaker, and has two potentiometers, respectively for the first stage and The second stage performs single-stage magnification adjustment, but the total magnification is the product of the two-stage multle, so the magnification will be adjusted to a large extent. (If the first level is adjusted to 20 times magnification, then if the second level is adjusted to 100 times, then the total magnification is 2000 times) Note: If the friends take the maximum magnification without telling the request, we will sh the goods at the default 1000 times. 1. Power supply voltage: 3.5-24V DC power supply 2. Current output: maximum 15-20MA (non-linear) 3. Voltage output: output = input voltage signal * magnification 4. Magnification: Total multle = first multle multle * second multle multle 5. Board size: length 45.3mm width 16.2mm 6. The two potentiometers on the board are rotated counterclockwise to increase the multle.
