LM2901/ LM2901A/ LM2903/ LM2903A
DUAL AND QUAD DIFFERENTIAL COMPARATORS
Description
The LM2901/2903 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 LM2901/2903 series comparators are designed to directly
interface with TTL and CMOS. When operating from both plus and
minus power supplies, the LM2901/2903 series comparators will
directly interface with MOS logic where their low power drain is a
distinct advantage over standard comparators.

Notes:
4. Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only; functional
operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
5. Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
6. Maximum power dissipation is a function of TJ(MAX), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is
PD = (TJ(MAX) − TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
7. Human body model, 1.5kΩ in series with 100pF.

Notes:
8. 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.
9. All limits are guaranteed by testing or statistical analysis. Limits over the full temperature are guaranteed by design, but not tested in production.
10. VO 1.4V, RS = 0Ω with VCC from 5V to 30V;
11. 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.
12. 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.
13. 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.
14. 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).
