If 500V input is on pin 3 this will results in 5V on the signal node (100:1). If U1 is set to 1X gain, output = 5V.\nIf 5V on pin 3 results in .05V on the signal node. If U1 is set to 50X gain, output = 2.5V.\nThis can be handy if you are sniffing an automotive ignition signal, that can spike up to 400 to 500V. \n\nIf 250V input is on pin 2, this will result in 5V on the signal node (50:1). If U1 is set to 1X gain, output = 5V. \nIf 50V input is on pin 2, this will result in 1V on the signal node (50:1). If U1 is set to 1X gain, output = 1V. \nIf 25V input is on pin 2, this will result in 1/2V on the signal node (50:1). If U1 is set to 10X gain, output = 5V.\nIf 5V input is on pin 2, this will result in 1/10V on the signal node (50:1). If U1 is set to 50X gain, output = 5V. \nThis is good for sniffing fuel injectors that might spike to 40 to 70V. \n\nIf 5V input is on pin 1, this will result in 5V on the signal node (1:1). If U1 is set to 1X gain, output = 5V. \nIf 1V input is on pin 1, this will result in 5V on the signal node (1:1). If U1 is set to 10X gain, output = 5V. \nIf .1V input is on pin 1, this will result in 5V on the signal node (1:1). If U1 is set to 50X gain, output = 5V. \nThis is good for signals you know will be 5V or less, including very small signals. \n\nSallenkey LPF 10kHz\nhttp://sim.okawa-denshi.jp/en/OPstool.php
