LM219/LM319
DESCRIPTION
The LM319 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. Further, they have higher gain and lower input currents than devices like the A710. The uncommitted collector of the output stage makes the LM319 compatible with RTL, DTL, and TTL as well as capable of driving lamps and relays at currents up to 25 mA. Although designed primarily for applications requiring operation from digital logic supplies, the LM319 series are fully specified for power supplies up to 15 V. 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 LM319 much more versatile than older devices like the A711.

NOTES: 1. VOS, IOS and IB specifications apply for a supply voltage range of VS = 15 V down to a single 5 V supply. 2. The offset voltages and offset currents given are the maximum values required to drive the output to within 1 V of either supply with a 1 mA load. Thus these parameters define an error band and take into account the worst case effects of voltage gain and input impedance. 2001 Aug 03 3
