The LF353 data sheet shows typical/min values of OL gain of 100/25 V/mV and worst case (over temp) as 15 V/mV. My assumption is that you arrive at these values through some combination of analysis and testing, but would like to know what the rationale is for these specs. This question is not really specific to the LF353. I'm just trying to council my students to abide by your worst case product specifications, but would like information from you to substantiate my claims.
Thanks!
