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.

Notes:
5. 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.
6. Short circuits from outputs to V
can cause excessive heating and eventual destruction.

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 ≤ T ≤ +125°C) are guaranteed by design, but not tested in
A
production.
11. V

from 5V to 30V.
CC
O
S
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 V
-1.5V (@ +25°C), but either or both inputs can go to +36V without damage, independent of the magnitude of V
.
CC
CC
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).

Application Information
General Information
The LM2901Q/2903Q series comparators are high-gain, wide-bandwidth devices, and like most comparators, can easily oscillate if the output lead
is inadvertently allowed to capacitive couple to the inputs via stray capacitance. This shows up only during the output voltage transition intervals as
the comparator changes states. Standard PC board layout is helpful as it reduces stray input-output coupling. Reducing the input resistors to
<10kΩ reduces the feedback signal levels and finally, adding even a small amount (1.0 to 10mV) of positive feedback (hysteresis) causes such a
rapid transition that oscillations due to stray feedback are not possible. Simply socketing the IC and attaching resistors to the pins will cause input-
output oscillations during the small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with relatively fast rise and
fall times, hysteresis is not required. All input pins of any unused comparators should be tied to the negative supply.
The bias network of the LM2901Q/2903Q series comparators establishes a quiescent current independent of the magnitude of the power supply
voltage over the range of from 2.0 VDC to 30 VDC
.
The differential input voltage may be larger than VCC without damaging the device. Protection should be provided to prevent the input voltages from
becoming negative more than -0.3 VDC (@ +25°C). An input clamp diode can be used as shown in the applications section.
The output of the LM2901Q/2903Q series comparators is the uncommitted collector of a grounded-emitter NPN output transistor. Many collectors
can be tied together to provide an output OR’ing function. An output pull-up resistor can be connected to any available power supply voltage within
the permitted supply voltage range and there is no restriction on this voltage due to the magnitude of the voltage applied to the VCC terminal of
LM2901/2903 series comparator package. The output can also be used as a simple SPST switch to ground (when a pull-up resistor is not used).
The amount of current the output device can sink is limited by the drive available (which is independent of VCC) and the β of this device. When the
maximum current limit is reached (approximately 16mA), the output transistor will come out of saturation and the output voltage will rise very
rapidly. The output saturation voltage is limited by the approximately 60Ω RSAT of the output transistor. The low offset voltage of the output
transistor (1.0mV) allows the output to clamp essentially to ground level for small load currents.
