型号：LM339(四通道电压比较器）

封装：SOP-14

LM339 四通道电压比较器的概述：

The LM339 series consists of four independent precision voltage comparators with an offset voltage specification as low as 2mV. The input common mode voltage range of these comparators includes ground,even when operated from a single power supply voltage. 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.

The LM339 series is designed to directly interface with

TTL and CMOS.

The LM339 series can be widely used in such applications as battery charger, cordless telephone, switching

power supply, DC-DC module and PC motherboard.

The LM339 series are available in 2 Packages: DIP-14

and SOIC-14.
