PJ393
Dual Voltage Comparator
The PJ393 is dual independent precision voltage
comparators capable of single- or split-supply
operation.
specifications as low as 2.0 mV make this device an
excellentground level with single-supply operation. Input
offset-voltage selection for many applications in consumer
automotive, and It is designed to permit a common mode
range-to- industrial electronics.
FEATURES
• Output voltage compatible with DTL, ECL, TTL, MOS
and CMOS Logic Levels
• Low input bias current -25 nA
• Low input offset current -5.0 nA
• Low input offset voltage --5.0 mV(max)
• Input common mode range to ground level
• Differential lnput voltage range equal to power supply
voltage
• Very low current drain independent of supply voltage -
0.4 mA
• Wide single-supply range - 2.0 Vdc to 36 Vdc
• Split-supply range - ±1.0 Vdc to ±18 Vdc

APPLICATIONS INFORMATION
This dual comparator feature high gain, wide bandwidth characteristics. This gives the device oscillation
tendencies if the outputs are capactively coupled to the inputs via stray capacitance. This oscillation manifests itself
during output transitions (VOL to VOH). To alleviate this situation input resistors <10KΩ should be used. The addition
of positive feedback (<10 mV) is also recommended.
It is good design practice to ground all unused pins.
Differential input voltages may be larger than supply voltage without damaging the comparator's inputs. Voltages
more negative than -0.3 V should not be used.
