Features (Typical unless otherwise noted) Rail-to-Rail input common-mode voltage range, guaranteed over temperature Rail-to-Rail output swing within 20 mV of supply rail, 100 k load Operates from 5V to 15V supply Excellent CMRR and PSRR 82 dB Ultra low input current 150 fA High voltage gain (RL = 100 k) 120 dB Low supply current (@ VS = 5V) 500 µA/Amplifier Low offset voltage drift 1.0 µV/°C 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 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 circuit configurations. 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.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
