Other Parts Discussed in Thread: OPA4322
Hello.
We used OPA2322 for Scanner application detect paper function.
We get problem about OPA2322 U3A pin 1 output ripple too big. Some OPA2322 is no problem. But some OPA2322 is problematic.
I think maybe is design issues. Please kindly reference on below information and need your help to provide suggestions to us. Thanks~
