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 greenmold compound and are qualified to AEC-Q100
Grade 1 and are Automotive Compliant supporting PPAPs.

Notes:
9. Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will
also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material
10. All limits are guaranteed by testing or statistical analysis. Limits over the full temperature (-40 TA +125°C) are guaranteed by design, but not tested
in production.
11. VO 1.4V, RS = 0with VCC from 5V to 30V.
12. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output
so no loading change exists on the input lines.
13. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (@ +25°C). The upper end of the
common-mode voltage range is VCC -1.5V (@ +25°C), but either or both inputs can go to +36V without damage, independent of the magnitude of VCC.
14. The response time specified is for a 100mV step input with 5mV overdrive. For larger overdrive signals 300ns can be obtained, see typical performance
characteristics.
15. Positive excursions of input voltage may exceed the power supply level. As long as other voltages remain within the common-mode range, the
comparator will provide a proper output stage. The low voltage state must not be less than -0.3V (or 0.3V below the magnitude of the negative power
supply, if used).
