Original question:

OPA862: It is not a differential output.

OPA862: It is not a differential output.

Part Number: OPA862
Other Parts Discussed in Thread: OPA892

Tool/software:

The signal input to the OPA862 is generated by an oscillator.
The circuit generated by the ICM7555 had differential outputs.
On the other hand, the circuit generated by the SIT2001BC does not have differential outputs.
Is there a possibility that this is the cause?

    Hi,

    Could you share where the OPA892 is connected in this circuit. I am a little confused as to what you are referring to. Also, for the previous prototype where the OPA862 was operating as expected, are the same devices connected to the circuit? Meaning the devices you shared are also in the previous working revision and the only difference is the input signal's frequency and the board layout/layers.

    Best Regards,

    Ignacio
