LM319 Comparator

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 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.

Part Number: LM393N

Function  : Low Power Dual Voltage Comparator

Package: DIP 8 Pin

Manufacturer: Philips Semiconductors

Pinout:LM393N Datasheet Philips

Description

The LM393N series consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0mV max. for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. These comparators also have a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage. The Device series was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, the Device series will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.
