General DescriptionThe LMC6492/LMC6494 amplifiers were specifically devel-
opedfor single supply applicationsthat operate from −40˚C +125˚C. This featureis well-suitedfor automotivesystems
becauseofthe wide temperature range. Aunique designto-
pology enables theLMC6492/LMC6494 common-mode volt-
age rangeto accommodate input signals beyondthe rails.
This eliminates non-linear output errorsdueto input signals
exceedinga traditionally limited common-mode voltage
range. The LMC6492/LMC6494 signal range hasa high
CMRR of82dBfor excellent accuracyin non-inverting circuit
configurations.
The LMC6492/LMC6494 rail-to-rail inputis complemented rail-to-rail output swing. This assures maximum dynamic
signal range whichis particularly importantin5V systems.
Ultra-low input currentof150fAand120dB open loop gain
provide high accuracyand direct interfacingwith high imped-
ance sources.
