        ?Comparator, Dual, Low Offset Voltage

        制造商:ON

        產品信息

        LM393 是雙電壓比較器集成電路。

        輸出負載電阻能銜接在可允許電源電壓范圍內的任何電源電壓上,不受 Vcc端電壓值的限制.此輸出能作為一個簡單的對地SPS開路(當不用負載電阻沒被運用),輸出部分的陷電流被可能得到的驅動和器件的β值所限制.當達到極限電流(16mA)時,輸出晶體管將退出而且輸出電壓將很快上升。


        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
