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 have been 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 operate 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 and the quad devices

available in SO-14 and TSSOP-14 with industry standard pinouts.

Both use green mold compound as standard.

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 LM2901/2903 series comparators are high gain, wide bandwidth devices, 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 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 and finally, adding even a small amount (1.0 to 10 mV) 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 LM2901/2903 series comparators establishes a quiescent current independent of the magnitude of the power supply

voltage over the range of from 2.0 V

The differential input voltage may be larger than V

voltages from going negative more than -0.3 V

The output of the LM2901/2903 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 V

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 V

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 R

(1.0 mV) allows the output to clamp essentially to ground level for small load currents.
