Micropower low-voltage rail-to-rail comparator

The TS331, TS332 and TS334 are single, dual and quad micropower and low-voltage comparators. They can operate with a supply voltage ranging from 1.6 V to 5 V with a typical current consumption as low as 20 μA. In addition, rail-to-rail inputs make them a perfect choice for low-voltage applications.

Their availability in tiny packages is a real advantage for overcoming space constraints.

The TS33x are specified for temperatures between -40 °C to +125 °C, making them ideal for a wide range of applications.
