I found in the books that "
Inverting op amps do not suffer from common-mode rejection ration effects when
the amplifier inputs are permanently at ground for dual supply applications or half
the supply voltage in single supply applications. The non-inverting amplifier
configuration has a common-mode voltage equal to the input signal."
But I not know why? for in single supply application above, I think the common mode voltage is half of the supply.
