RH119
High Performance
Dual Comparator
DESCRIPTION
The RH119 dual comparator features low input offset
voltage and offset current, high voltage gain, guaranteed
common mode rejection and input protection diodes.
The RH119 is capable of operation over a supply range
from 5V to ±15V and can drive 25mV leads from each open
collector output. A separate GND pin allows the RH119 to
isolate system grounds.
The wafer lots are processed to Linear Technology’s in-
house Class S flow to yield circuits usable in stringent
military applications.
