AUTOMOTIVE COMPLIANT DUAL AND QUAD DIFFERENTIAL COMPARATORS
Description
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 LM2901Q/2903Q series comparators are designed to directly
interface with TTL and CMOS.
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.
All use “green” mold compound and are qualified to AEC-Q100
Grade 1 and are Automotive Compliant supporting PPAPs.
