Description The LMC6582/4 is a high performance operational amplifier which can operate over a wide range of supply voltages with guaranteed specifications at 1.8V, 2.2V, 3V, 5V, and 10V.
The LMC6582/4 provides an input common-mode voltage range that exceeds both supplies. The rail-to-rail output swing of the amplifier assures maximum dynamic signal range. This rail-to-rail performance of the amplifier, combined with its high open-loop voltage gain makes it unique among rail-to-rail CMOS amplifiers. The LMC6582/4 is an excellent choice for circuits where the input common-mode voltage range is a concern.
The LMC6582/4 has been designed specifically to improve system performance in low voltage applications. Guaranteed operation down to 1.8V means that this family of amplifiers can operate at the end of discharge (EOD) voltages of several popular batteries. The amplifier's 80 fA input current, 0.5 mV offset voltage, and 82 dB CMRR maintain accuracy in battery-powered systems.
For a single, dual or quad CMOS amplifier with similar specs and a powerdown mode, refer to the LMC6681/2/4 datasheet.
