If the first level is adjusted to 20 times magnification, then if\nthe second level is adjusted to 100 times, then the total magnification is\n2000 times. Note: the default of this LM358 Amplifier is 1000 times.\nParameters: 1. Power supply voltage: 3.5-24V DC power supply. 2. Current\noutput: maximum 15-20MA (non-linear). 3.
