I used a AD8351S to convert a single ended signal to differential signal for ADC input.
My schematic is pasted as below.
When I change R26 and R27 to 0 or 25 Ohm, the output has a oscillation phenomenon, and the output frequency changed with R26 and R27. In this case, input is floated.
When I test the DUT in low temperature to -10℃, the output seems add some peaking signals.
How CAN I solve these problems?
