Optional offset nulling circuit
WebNov 7, 2016 · Hi all. I am looking for a way to utilize resistors/potentiometer to adjust the offset at the input of a fully differential op amp to be close to zero with little affect on gain. I have simulated a pot attached at the negative input before the input resistor but it affects gain. Anyone know of...

You can make a 3 op amp IA (a la INA111) with an LM324, and adjust the offset by injecting a voltage on the REF input, as has been mentioned. The problem is, you have to set the gain first, and then set the offset. If you set the offset first, then changing the gain will change the offset. fish caneWebMay 22, 2024 · Any DC offset is also affected by the gain change, in effect causing the control signal to “leak” into the output. This can produce many undesirable side effects, including clicking and popping noises if the circuit is used as an audio VCA. By nulling the output offset, these effects are eliminated. can a cat get stung by a beeWebNulling Input Offset Voltage of Operational Amplifiers Bao Nguyen and W.
