The LTC

1040 is a monolithic CMOS dual comparator

manufactured using Linear Technology’s 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.
