ISL28197

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.

Applications

• 2-Cell Alkaline Battery-Powered/Portable Systems
• Window Comparators
• Threshold Detectors/Discriminators
