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.
