The LTC
1042 is a monolithic CMOS window comparator
manufactured using Linear Technology’s enhanced
LTCMOS
silicon gate process. Two high impedance
voltage inputs, CENTER and WIDTH/2, define the middle
and width of the comparison window. Whenever the input
voltage, VIN, is inside the window the WITHIN WINDOW
output is high. The ABOVE WINDOW output is high
whenever VIN is above the window. By interchanging VIN
and CENTER, the ABOVE WINDOW output becomes
BELOW WINDOW and is high if VIN is below the window.
Sampling techniques provide high impedance voltage
inputs that can common mode to both supply rails
(V+ and GND). An important feature of the inputs is their
non-interaction. Also the device is effectively “chopper
stabilized,” giving it extremely high accuracy over
all conditions of temperature, power supply and input
voltage range.
Another benefit of the sampling techniques used to design
the LTC1042 is the extremely low power consumption.
When the device is strobed, it internally turns on the power
to the comparators, samples the inputs, stores the outputs
in CMOS latches and then turns off power to the compara-
tors. This all happens in about 80s. Average power can be
made small, almost arbitrarily, by lowering the strobe rate.
The device can be self-strobed using an external RC
network or strobed externally by driving the OSC pin with
a CMOS gate.
