Low power dual voltage comparator
NJM393C
Features
• Wide single supply voltage range or dual supplies
+2V to +36V or ±1V to ±18V
• Very low supply current : 0.45mA typ. at Vcc+=5V
• Low input bias current: 20nA typ.
• Low input offset current: 0.5nA typ.
• Low input offset voltage: 0.5mV typ.
• Input common-mode voltage range includes ground
• Low output saturation voltage: 80mV typ. (Isink = 4mA)
• Differential input voltage range equal to the supply voltage
• TTL, DTL, ECL, MOS, CMOS compatible outputs
• Internal ESD protection
Human body model (HBM) ±2000V typ.
Description
The NJM393C consist of two independent low power voltage comparators
designed specifically to operate from a single supply over a wide range of
voltages. Operation from split power supplies is also possible.
These comparators 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.
