5.2 Low Voltage Operation

Comparators are the common devices by which analog signals interface with digital circuits. The LMC7211-N has been designed to operate at supply voltages of 2.7V without sacrificing performance to meet the demands of 3V digital systems.

At supply voltages of 2.7V, the common-mode voltage range extends 200mV (specified) below the negative supply. This feature, in addition to the comparator being able to sense signals near the positive rail, is extremely useful in low voltage applications.

LMC7211-N Even at Low-Supply Voltage of 2.7V, an Input Signal which Exceeds the Supply Voltages Produces No Phase Inversion at the OutputFigure 5-1 Even at Low-Supply Voltage of 2.7V, an Input Signal which Exceeds the Supply Voltages Produces No Phase Inversion at the Output

At V+ = 2.7V propagation delays are tPLH = 420ns and tPHL = 450ns with overdrives of 100 mV.
