We are trying to use the schematic provided in UG-160 (ADF4108) eval board user manual.
Can we replace the OP184, which uses a single rail 15V supply, with an OP27, which uses a dual rail +/-15V supply.
Can we avoid using the -15V supply rail and ground…
OP184的外围电路怎么设计的？
ADA4084-1 is next generation OP184; higher speed, less power, less money.
Also see AN-940
What is your sensor/source impedance?

HI Anna：
thank you for your answer，
But I've added the REF pin a voltage（2.5V） by op184，Is this not a right way？
how should I set？

nessler,
My personal favorite is the OP184, but it does not come in a DIP. It's +/-15V, low noise, RR in and out,
better gbw than the 741, etc.
For a dual, the new ADA4084-2. Maybe in a year or two there will be a single.
