NOYITO LM358 100 Gain Signal Amplification Module Operational Amplifier Module Working Voltage DC5 to 12V (Pack of 2)

so now in this video we're going to use the LM 358 op-amp again it's a single supply op amp we're going to use a single supply or it could use the dual supply with it but any case we're going to get a voltage gain of two so the voltage orders going to be two times what the voltage in the formula for this the gain is 1 plus resistor 2 divided by resistor 1 since they're equal value that makes the math easy we end up with 110 K divided by 10k is 1 and any case we have the voltage in we're going to set with a trim pot right there and you can see here that we have a voltage divider since they're equal value we'll have half of the value at the inverting input there that we have at the output and voltage in well when it's higher will raise the voltage until the voltage at the inverting input reaches the same voltage that we have at the voltage at the non-inverting input so you need twice the
