LMC6494AEM/NOPB

The LMC6494AEM/NOPB is a quad CMOS Operational Amplifier with rail-to-rail input and output. The LMC6494 amplifier was specifically developed for single supply applications that operate from -40 to +125°C. An unique design topology enables the 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 LMC6494 signal range has a high CMRR of 82dB for excellent accuracy in non-inverting circuit configurations. The 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 150fA and 120dB open loop gain provide high accuracy and direct interfacing with high impedance sources.
