Detailed Product Description

 

LM119/LM219/LM319

High Speed Dual Comparator

 

General 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 5V logic supply and ground. Further, they have higher gain and lower input currents than devices like 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 up to 25 mA.

 

The LM319A offers improved precision over the standard LM319, with tighter tolerances on offset voltage, offset current, and voltage gain.

 

Features

• Two independent comparators

• Operates from a single 5V supply

• Typically 80 ns response time at ±15V

• Minimum fan-out of 2 each side

• Maximum input current of 1 µA over temperature

• Inputs and outputs can be isolated from system ground

• High common mode slew rate

 

Although designed primarily for applications requiring operation from digital logic supplies, the LM119 series are fully specified for power supplies up to ±15V. It 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 much more versatile than older devices like 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.
