Which LDO is the AD8422 suitable for?

I have an AD8422 instrumentation amplifier.
I need a +-5V source to supply the AD8422 instrumentation amplifier.

I am using ADR4550 as reference voltage.
(1.) I already have the ADR4550 as a reference voltage do I still need an LDO?
(2.) Excuse me, how do I generate +-5V to power the AD8422 instrumentation amplifier?Is it to use two LDOs or ADR4550s and reverse the +- pins of one of them?

By the way, my signal V+ is 2.2V, V- is 1.4V, after 10 times the output is +-4V?

Thanks Reply
