The LTC
1040 is a monolithic CMOS dual comparator
manufactured using Linear Technology’s enhanced
LTCMOS
TM 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.
