Description
These devices consist of two independent
precision voltage comparators, designed to
operate with single or dual supplies.
These differential comparators use the
STMicroelectronics silicon lin MOS process giving
them an excellent consumption-speed ratio.
These devices are ideally suited for low
consumption applications.
