Product Summary
The LM319N is a precision high speed dual comparator fabricated on a single monolithic chip. The LM319N is 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 LM319N compatible with RTL, DTL and TTL as well as capable of driving lamps and relays at currents up to 25 mA. The LM319N offers improved precision over the standard LM319, with tighter tolerances on offset voltage, offset current, and voltage gain.
