LM119QML High Speed Dual Comparator
July 24, 2008
LM119QML
High Speed Dual Comparator
General Description
The LM119 is a precision high speed dual comparator fabri-
cated on a single monolithic chip. It is designed to operate
over a wide range of supply voltages down to a single 5V logic
supply and ground. Further, it has higher gain and lower input
currents than devices like the LM710. The uncommitted col-
lector of the output stage makes the LM119 compatible with
RTL, DTL and TTL as well as capable of driving lamps and
relays at currents up to 25 mA.
Although designed primarily for applications requiring opera-
tion from digital logic supplies, the LM119 is fully specified for
power supplies up to ±15V. It features faster response than
the LM111 at the expense of higher power dissipation. How-
ever, the high speed, wide operating voltage range and low
package count make the LM119 much more versatile than
older devices like the LM711.
