NCS2220A
Low Voltage Comparator
The NCS2220A is an industry first sub−one volt, low power dual
comparator. This device consumes only 7.5 mA per Comparator of
supply current. It is guaranteed to operate at a low voltage of 0.85 V
which allows it to be used in systems that require less than 1.0 V and is
fully operational up to 6.0 V which makes it convenient for use in both
3.0 V and 5.0 V systems. Additional features include no output phase
inversion with overdriven inputs, internal hysteresis, which allows for
clean output switching, and rail−to−rail input and output performance.
The NCS2220A is available in the tiny UDFN 1.6 X 1.6 package.

OPERATING DESCRIPTION
The NCS2220A is an industry first sub−one volt, low
power comparator. This device is designed for rail−to−rail
input and output performance. This device consumes only
10ĂmA/Comparator of supply current while achieving a
typical propagation delay of 1.1 ms at a 20 mV input
overdrive. Figures 10 and 11 show propagation delay with
various input overdrives. This comparator is guaranteed to
operate at a low voltage of 0.85 V up to 6.0 V. This is
accomplished by the use of a modified analog CMOS
process that implements depletion MOSFET devices. The
common−mode input voltage range extends 0.1 V beyond
the upper and lower rail without phase inversion or other
adverse effects. This device has a typical internal hysteresis
of "8.0 mV. This allows for greater noise immunity and
clean output switching.
Output Stage
The NCS2220A has a complementary P and N Channel
output stage that has capability of driving a rail−to−rail
output swing with a load ranging up to 5.0 mA. It is designed
such that shoot−through current is minimized while
switching. This feature eliminates the need for bypass
capacitors under most circumstances.
