we are facing a glitch issue in the ADG849 input/output. The problem goes like this. We are feeding Square wave of 1ms with 2.5Vpp wave on S1 (Pin-4) and S2 (Pin-6) has constant DC voltage generated from the log detector/op-amp circuit. We are observing glitch on S2 and Output D (Pin-1) on every raising and falling edge of square present on the S1. I have attached circuit for the reference. Please let us know what is causing this issue?
