WebThe maximum output slew rate in the photo is 70V/μs. This rate is set by the 70mA current limit driving 1nF As a performance benchmark, the LM118 takes 1.2μs to peak detect and settle, given the same amplitude input. This slower response is due in part to the much lower slew rate and lower phase margin of the LM118.
