Hi Quang, Before, when it was my first time to use the OSK function in the evaluation board, I also had the same confusion with you. I read the datasheet many times about the OSK function, but I only...
View ArticleUnderstanding the ADA4091-4 Input protection circuitry
I have a circuit design which has an op amp with +/-15V rails feeding into an ADA4091-4 on 0->3.3V. There is 9.4k between the 2 parts of the circuit. Is this sufficient to protect the 4091 in light...
