LMC6681 - National Semiconductor

LMC6681 Low Voltage / Rail-To-Rail Input and Output CMOS

The LMC6681/2/4 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 LMC6681/2/4 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 rai.
