General Description
The TS2903 is dual independent precision voltage comparators capable of single-supply or split-supply operation. The
specifications as low as 2.0 mV make this device an excellent ground level with single-supply operation. Input
offset-voltage selection for many applications in consumer automotive, and It is designed to permit a common mode
range-to- industrial electronics.
The TS2903 is offered in 8 pin SOP-8 and DIP-8 package.
