Features
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 Performing single-stage magnification adjustment, but the total scaling is the product of the two-stage multiple, so the magnification will be adjusted to a large extent.
Specifications
Power supply voltage:3.5-24V DC power supply
Current output:maximum 15-20MA (non-linear)
Voltage output:output = input voltage signal * magnification
Magnification:Total multiple = first multiple multiple * second multiple multiple
Board size:length 45.3mm width 16.2mm
Note
1. The maximum multiple is 1000 times.
2.The two potentiometers on the board are rotated counterclockwise to increase the multiple.
