    ... This eliminates non-linear output errors due to input signals exceeding a traditionally limited common-mode volt- age range. The LMC6492/LMC6494 signal range has a high CMRR for excellent accuracy in non-inverting circuit configurations. The LMC6492/LMC6494 rail-to-rail input is complemented by rail-to-rail output swing ...
