产品信息

lm393 是双电压比较器集成电路。

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
