LTC1040CN#PBF

LTC1040 is a monolithic CMOS dual comparator manufactured using Linear Technology’s enhanced LTCMOSTM 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. It is used in application like battery-powered systems, remote sensing, window comparator, BANG-BANG controllers etc.
