The LTC1040 is a monolithic CMOS dual comparator manufactured using Analog Devices' enhanced LTCMOS silicon gate process. Extremely low operating power levels are achieved by internally switching the comparator ON for short periods of time. The CMOS output logic holds the output information continuously while not consuming any power.

In addition to switching power ON, a switched output is provided to drive external loads during the comparator’s active time. This allows not only low comparator power, but low total system power.

Sampling is controlled by an external strobe input or an internal oscillator. The oscillator frequency is set by an external RC network.

Each comparator has a unique input structure, giving two differential inputs. The output of the comparator will be high if the algebraic sum of the inputs is positive and low if the algebraic sum of the inputs is negative.
