MAX4475 alternative

Q 

At the moment we are using an opamp from Maxim for all our amplifier design
(MAX4475). But the MAX4475 is not an input rail-to-rail opamp so we are
searching for a new opamp for our futures designs.

What we need is a low noise, low power (0V to 3V3) input/output rail-to-rail
opamp for filter and buffer applications (with unitary gain) and we really want
to reach at least 3V1 for buffer applications.
So we wonder which opamp that meets these specifications can you propose to us
to replace the MAX4475 that we are using ?

If you don't have further specification for your new designs (how low is low
noise and how low is low power) -> please check out the following amplifiers
(also attached in Excel).
