Description
NJM390AF, NJM390AF3
The NJM390A/NJM391A are single comparator designed specifically to
operate from a single supply over a wide range of voltages. Operation from split
power supplies is also possible.
The NJM390A/391A also have a unique characteristic in that the input
common-mode voltage range includes ground even though operated from a
single power supply voltage.

1. At output switch point, Vo = 1.4V, RS = 0 with VCC+ from 5V to 30V, and over the full common-mode range (0V to VCC+ - 1.5V).
2. The direction of the input current is out of the IC due to the PNP input stage.
3. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the common-mode range, the
comparator will provide a proper output state. The low input voltage must not be less than –0.3V (or 0.3V below the negative power supply, if used).
4. The response time specified is for a 100mV input step with 5mV overdrive.
5. This parameter is not 100% test.
