Hello, you guys! Nice to meet you. May I inquire whether the big resistance grounding resistors, such as R1 and R2 in the figure, used to give a DC loop to the AD8421's input will introduce additional thermal noise? If so, how should the noise generated be calculated? The circuit I designed refers to the related pdf:https://www.utmel.com/components/ad8421-amplifier-pinout-datasheet-schematic?id=745shown below. Thanks! K  ------------- Have more fun at Electronic... |

Interesting. What's the application here? There is a formula for calculating Johnson noise (online calculator here) but other than that I don't think I'm savvy enough with analog electronics to help you. ------------- |
