Unformatted text preview: LM119/LM219/LM319 High Speed Dual Comparator General Description The LM119 series are precision high speed dual compara- tors fabricated on a single monolithic chip. They are de- signed 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 cur- rent, and voltage gain. Although designed primarily for applications requiring opera- tion from digital logic supplies, the LM119 series are fully specified for power supplies up to 15V. It features faster re- sponse than the LM111 at the expense of higher power dis- sipation. 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 -55C to +125C, the LM219 is specified from -25C to +85C, and the LM319A and LM319 are specified from 0C to +70C.
