FEATURES 2(Typical Unless Otherwise Noted) - Rail-to-Rail Input mon-Mode Voltage Range, Ensured Over Temperature - Rail-to-Rail Output Swing within 20 m V of Supply Rail, 100 kΩ Load - Operates from 5V to 15V Supply - Excellent CMRR and PSRR 82 d B - Ultra Low Input Current 150 f A - High Voltage Gain (RL = 100 kΩ) 120 d B - Low Supply Current (@ VS = 5V) 500 μA/Amplifier - Low Offset Voltage Drift 1.0 μV/°C APPLICATIONS - Automotive Transducer Amplifier - Pressure Sensor - Oxygen Sensor - Temperature Sensor - Speed Sensor 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 monmode 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.
