Hi Vladimir,
I just want verify your question. You want to disconnect the output of one of the op amp once it is not active? I'm seeing you have AD8534 for one of the DAC and AD8532 for the other DAC…
Hi Vladimir,
I can't recommend to use conventional diodes in this application.You can't achieve best performance of your circuit in this condition.
Since you are already modifying your board…
Hi, Phil. In the figure, part of the circuit. Maybe there is nothing wrong with the signals from the outputs of the operational amplifiers can not simultaneously appear at the output due to a temporary demarcation work DACs. But I am concerned about their influence in the static mode. In the static mode, the output voltage is equal to 5V. The main thing for me - the absence of a possible short circuit. When designing a circuit I made a mistake and did not notice that connect the output of the operational amplifiers is now trying to address this shortcoming.
