The LMC6492/LMC6494 amplifiers were specifically developed for single supply applications
that operate from −40°C to +125°C. This feature is well-suited for automotive systems because of
the wide temperature range. A unique design topology enables the LMC6492/LMC6494 common-mode
voltage range to accommodate input signals beyond the rails. This eliminates non-linear output
errors due to input signals exceeding a traditionally limited common-mode voltage range. The
LMC6492/LMC6494 signal range has a high CMRR of 82 dB for excellent accuracy in non-inverting
The LMC6492/LMC6494 rail-to-rail input is complemented by rail-to-rail output swing. This
assures maximum dynamic signal range which is particularly important in 5V systems.
Ultra-low input current of 150 fA and 120 dB open loop gain provide high accuracy and
direct interfacing with high impedance sources.
