This feature is well-suited for Range, Ensured Over Temperature automotive systems because of the wide temperature • Rail-to-Rail Output Swing within 20 mV of range. A unique design topology enables the LMC6492/LMC6494 common-mode voltage range to Supply Rail, 100 k Ω Load accommodate input signals beyond the rails. This • Operates from 5V to 15V Supply eliminates non-linear output errors due to input • Excellent CMRR and PSRR 82 dB signals exceeding a traditionally limited common- • Ultra Low Input Current 150 fA mode voltage range. The LMC6492/LMC6494 signal range has a high CMRR of 82 dB for excellent • High Voltage Gain (RL = 100 kΩ) 120 dB accuracy in non-inverting circuit configurations. • Low Supply Current (@ VS = 5V) 500 The LMC6492/LMC6494 rail-to-rail input is μA/Amplifier complemented by rail-to-rail output swing. This • Low Offset Voltage Drift 1.0 μV/°C assures maximum dynamic signal range which is particularly important in 5V systems. APPLICATIONS Ultra-low input current of 150 fA and 120 dB open • Automotive Transducer Amplifier loop gain provide high accuracy and direct interfacing • Pressure Sensor with high impedance sources. • Oxygen Sensor • Temperature Sensor • Speed Sensor Connection Diagram Figure 1. 8-Pin PDIP/SOIC - Top View Figure 2. 14-Pin PDIP/SOIC - Top View 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
