AUTOMOTIVE COMPLIANT DUAL AND QUAD DIFFERENTIAL COMPARATORS
Description
Pin Assignments
The LM2901Q/2903Q series comparators consist of four and two
independent precision voltage comparators with very low input offset
voltage specification. They are designed to operate from a single
power supply over a wide range of voltages; however operation from
split power supplies is also possible. They offer low power supply
current independent of the magnitude of the power supply voltage.

The LM2903Q dual devices are available in SO-8, MSOP-8 and
TSSOP-8; and the LM2901Q quad devices are available in SO-14
and TSSOP-14 - all are in industry-standard pinouts.
