Low Offset Voltage
Dual Comparators
The LM393 series are dual independent precision voltage
comparators capable of single or split supply operation. These devices
are designed to permit a common mode range−to−ground level with
single supply operation. Input offset voltage specifications as low as
2.0 mV make this device an excellent selection for many applications
in consumer, automotive, and industrial electronics.

Maximum ratings are those values beyond which device damage can occur. Maximum ratings applied to the device are individual stress limit
values (not normal operating conditions) and are not valid simultaneously. If these limits are exceeded, device functional operation is not implied,
damage may occur and reliability may be affected.
1. The maximum output current may be as high as 20 mA, independent of the magnitude of VCC, output short circuits to VCC can cause
excessive heating and eventual destruction.
2. NCV2903 is qualified for automotive use.

3. The maximum output current may be as high as 20 mA, independent of the magnitude of VCC, output short circuits to VCC can cause
excessive heating and eventual destruction.
4. At output switch point, VO1.4 Vdc, RS = 0 with VCC from 5.0 Vdc to 30 Vdc, and over the full input common mode range (0 V to
VCC = −1.5 V).
5. Due to the PNP transistor inputs, bias current will flow out of the inputs. This current is essentially constant, independent of the output state,
therefore, no loading changes will exist on the input lines.
6. Input common mode of either input should not be permitted to go more than 0.3 V negative of ground or minus supply. The upper limit of
common mode range is VCC −1.5 V.
7. Response time is specified with a 100 mV step and 5.0 mV of overdrive. With larger magnitudes of overdrive faster response times are
obtainable.
8. The comparator will exhibit proper output state if one of the inputs becomes greater than VCC, the other input must remain within the common
mode range. The low input state must not be less than −0.3 V of ground or minus supply.

APPLICATIONS INFORMATION
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.
These dual comparators feature high gain, wide
bandwidth characteristics. This gives the device oscillation
tendencies if the outputs are capacitively coupled to the
inputs via stray capacitance. This oscillation manifests itself
during output transitions (VOL to VOH). To alleviate this
situation, input resistors < 10 k should be used.
