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.
