Specification: Item Type: Voltage amplifier Supply Voltage: 3.5-24V DC power supply Current Output: Maximum 15-20MA (non-linear) Voltage Output: Output = input voltage signal x magnification Magnification: Total multiple = First multiple multiple x second multiple Board Size: Length: Approx. 45.3mm / 1.8in, Width: Approx. 16.2mm / 0.6 in Features: 1It can amplify signals that are millivolts or even weaker, and the two potentiometers on the board rotate in counterclockwise to increase the multiple. 2LM358 is the core two-stage operational amplifier, which can amplify DC weak signals, such as DC voltage signals and DC pulse signals. 3There are two potentiometers for single-stage magnification adjustment of the first and second stages, respectively. 4But the total magnification is the product of the multiple of these two, so the magnification will be adjusted to a large extent. 5If the first level is adjusted to 20 times magnification, then if the second level is adjusted to 100 times, and the total magnification is 2000 times.
