Utility of VDET and VREF for ADMV7810 (RF amplifier with power detector)

Category: Datasheet/Specs
Product Number: ADMV7810

Hello,

I'm currently working on the ADMV7810 and I'm wondering about the VDET and VREF signals.

Do they have to be connected to an AOP subtractor circuit for the amplifier to work, or can we leave them floating if we don't particularly want to know the output power?

Thanks in advance
