Introduction
The ISL28196 and ISL28197 are CMOS rail-to-rail input and
output (RRIO) micropower comparators. These devices are
designed to operate from single supply (1.8V to 5.5V) and
have an input common mode range that extends to the
positive rail and to the negative supply rail for true rail-to-rail
performance. The CMOS output can swing within tens of
millivolts to the rails. Featuring worst case maximum supply
currents of only 4.5µA and 2µA for the ISL28196 and
ISL28197 respectively, these comparators are ideally suited
for solar and battery powered applications.

Input Protection
All input terminals have internal ESD protection diodes to both
positive and negative supply rails, limiting the input voltage to
within one diode beyond the supply rails. Both the ISL28196
and ISL28197 have a maximum input differential voltage that
extends beyond the rails (
Rail-to-Rail Output
A pair of complementary MOSFET devices are used to
achieve the rail-to-rail output swing. The NMOS sinks
current to swing the output in the negative direction. The
PMOS sources current to swing the output in the positive
direction. The ISL28196 and ISL28197 with a 100kΩ load
will swing to within 6mV of the positive supply rail and within
3mV of ground.
