Im using the AD8672 on the dual op amp evaluation board to provide 2 output channels.
Both amplifier A and B are given the same 30us input signal. Amplifier A is behaves normally as long as Amplifier B is not connected to a scope (50ohm termination). Can anyone explain to me why this happening?
Ive attached the schematic as well as 2 scope captures.
Ch1 is the input signal.
Ch2 is the output of Amplifier A.
Ch3 is the output of Amplifier B.
