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.
