Dual voltage comparator
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
µA710.
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
µA711.

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.
