OPERATING DESCRIPTION
The NCS2200 series is an industry first sub−one volt, low
power comparator family. This series is designed for
rail−to−rail input and output performance. These devices
consume only 10 mA 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 family 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 series is available in the SOT−23−5
package. Additionally, the NCS2200 device is available in
the tiny DFN 2x2.2 package and the SC70−5 package.
NCS2200A is available in UDFN package.
Output Stage
The NCS2200 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.
The NCS2202 has an open drain N−channel output stage
that can be pulled up to 6.0 V (max) with an external resistor.
This facilitates mixed voltage system applications.
