LM393 比较器，双通道，低偏移电压

LM393 是双电压比较器集成威廉希尔官方网站 。

输出负载电阻能衔接在可允许电源电压范围内的任何电源电压上，不受 Vcc端电压值的限制.此输出能作为一个简单的对地SPS开路(当不用负载电阻没被运用)，输出部分的陷电流被可能得到的驱动和器件的β值所限制.当达到极限电流(16mA)时，输出晶体管将退出而且输出电压将很快上升。

The LM393 series are dual independent precision voltage comparators capable of single or split supply operation. These devices are designed to permit a common mode range-to-ground level with single supply operation. Input offset voltage specifications as low as 2.0 mV make this device an excellent selection for many applications in consumer automotive and industrial electronics.

• Wide Single-Supply Range: 2.0 Vdc to 36 Vdc

• Split-Supply Range: +/-1.0 Vdc to +/-18 Vdc

• Very Low Current Drain Independent of Supply Voltage: 0.4 mA

• Low Input Bias Current: 25 nA

• Low Input Offset Current: 5.0 nA

• Low Input Offset Voltage: 2.0 mV (max) LM393A 5.0 mV (max) LM293/393

• Input Common Mode Range to Ground Level

• Differential Input Voltage Range Equal to Power Supply Voltage

• Output Voltage Compatible with DTL, ECL, TTL, MOS, and CMOS Logic Levels

• ESD Clamps on the Inputs Increase the Ruggedness of the Device without Affecting Performance
