2 Description
The LM119 series are precision high-speed dual
comparators fabricated on a single monolithic chip.
They are designed to operate over a wide range of
supply voltages down to a single 5-V logic supply and
ground. They have higher gain and lower input
currents than devices such as the LM710. The
uncommitted collector of the output stage makes the
LM119 compatible with RTL, DTL, and TTL, as well
as capable of driving lamps and relays at currents of
up to 25 mA.
The LM319A offers improved precision over the
standard LM319, with tighter tolerances on offset
voltage, offset current, and voltage gain.
Although designed primarily for applications requiring
operation from digital logic supplies, the LM119 series
are fully specified for power supplies up to ±15 V.
The series features faster response than the LM111,
at the expense of higher power dissipation. However,
the high-speed, wide operating voltage range and low
package count make the LM119 more versatile than
older devices such as the LM711.
The LM119 is specified from −55°C to +125°C, the
LM219 is specified from −25°C to +85°C, and the
LM319A and LM319 are specified from 0°C to +70°C.
