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.
The dual devices are available in SO-8, TSSOP-8, and MSOP-8,
and
the quad devices available in SO-14 and TSSOP-14
with industry
standard pinouts. Both use green mold compound as standard.

Notes: 4. Stresses beyond t hose listed under Absolute Maximum Ratings can 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 can 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.

Application Information
General Information
The LM2901/2903 series com parators are high-gain, wide bandwidth devices. Like most comparators, the s eries 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 comparators change 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. Finally, adding even a small amount (1.0mV 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 fal l times, hysteresis is not required. All i nput pins of any unused comparators should be t i ed to the negative supply.
The bias network of the LM2901/2903 series comparators establishes a quiescent current independent of the magnitude of the power supply
voltage over the range of from 2.0VDC to 30VDC.
The differential input voltage may be larger than VCC without damaging the device. Protection should be provided to prevent the input voltages f rom
going negative more than -0.3VDC (@ +25°C). An input clamp diode can be used as shown in the applications section.
The output of the LM2901/2903 series comparators is the uncommitted collector of a grounded-emitter NPN out put transistor. Many collectors can
be tied together to provide an output ORing 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 comparat or 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 limit ed 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
transist or (1. 0mV) allows the output to clamp essenti al l y to ground level for small load currents.
