Hello,
Now I am considering non inverting amplifier circuit (gain 2) using OPA355.
Layout example is shown in figure 40 on OPA355 data sheet.
"Noninverting input terminated in 50ohm" is recommended on figure 40.
I would like to confirm the meaning of this recommendation of 50ohm termination.
I am wondering if it is necessary to add a 50ohm terminating resistor to the + input of the non-inverting amplifier circuit.
Further, Place another opamp circuit at the signal source in the immediate vicinity of this non-inverting amplifier.
Regards,
MESH
