Data Sheet FN6152.3November 5, 2007

Ultra-Small, 800nA and 2.5µA Single
Supply, Rail-to-Rail Input/Output (RRIO)
Comparators

The ISL28196 and ISL28197 are micropower comparators
optimized for low-power applications. The parts are
designed for single-supply operation from 1.8V to 5.5V. The
ISL28197 typically consumes 800nA of supply current and
the ISL28196 typically consumes 2.5µA of supply current.
Both parts feature rail-to-rail input and output swing (RRIO),
allowing for maximum battery usage. The ISL28196 features
a propagation delay of 150µs and the ISL28197 features a
propagation delay of 0.6ms.

Equipped with an ENABLE pin (EN), both parts draw
typically 2nA when off. The combination of small footprint,
low power, single supply, and rail-to-rail operation makes
them ideally suited for all battery operated devices.
