LMC6492 Datasheet | National Semiconductor

Description 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 mon-mode voltage range to acmodate input signals beyond the rails. This eliminates non-linear output errors due to input signals exceeding a traditionally limited mon-mode voltage range. The LMC6492/LMC6494 signal range has a high CMRR of 82 d B for excellent accuracy in non-inverting circuit configurations. The LMC6492/LMC6494 rail-to-rail input is plemented 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 f A and 120 d B open loop gain provide high accuracy and direct interfacing with high impedance sources.
