Standard Open-Collector Comparator - BA2901SF

General purpose BA8391G/BA10393/BA10339 family and high reliability BA2903/BA2901 family integrate one, two or four independent high gain voltage comparator. Some features are the wide operating voltage that is 2 to 36[V] (for BA8391G, BA10393, BA2903, BA2901 family), 3 to 36[V] (for BA10339 family) and low supply current. Therefore, this series is suitable for any application.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
