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 it, same as the OP184?
The OP27 is not a rail-to-rail input and output part, unlike the OP184. With a single 15V supply, you will get very little input and output range from the amplifier, and this is probably not the best choice for this application.
You can take a look at the ADA4625-1. It is especially suited for loop filter applications and has a very thorough discussion on page 22 of the datasheet.
Let me know if this suits your purposes.
Thanks on that.
I am looking for enhanced parts as alternatives to the OP184. Please do let me know of any.
By enhanced parts, do you mean parts with extended temperature ranges?
I am referring here to Mil-grade OpAmps best suited for usage with ADF4108 and HMC509 VCO.
OpAmps with Single voltage Supply and availability in ADISimPLL library would be preferred.
