The LMC6492 and LMC6494 (LMC649x) amplifiers were specifically developed for single-supply applications that operate from −40°C to +125°C. This feature is an excellent choice for automotive systems because of the wide temperature range. A unique design topology enables the LMC649x 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 LMC649x signal range has a high CMRR of 82dB for excellent accuracy in noninverting circuit configurations.

The LMC649x rail-to-rail input is complemented by rail-to-rail output swing. This configuration provides maximum dynamic signal range and is particularly important in 5V systems.

An ultra-low input current of 150fA and a 120dB open-loop gain provide high accuracy and direct interfacing with high-impedance sources.
