型号：LM393(双电压比较器）

封装：DIP-8

LM393 双电压比较器的概述：

The LM393 series consists of two independent precision voltage comparators with an offset voltagespecification as low as 1mV.

The input common modevoltage 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 LM393 series is designed to directly interface with TTL and CMOS.

The LM393 series can be widely used in applications such as battery charger, cordless telephone,switching power supply, DC-DC module and PC motherboard.

The LM393 series are av ailable in standard packages of DIP-8 and SOP-8.
