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.

Features

1. Wide Single−Supply Range: 2.0 Vdc to 36 Vdc

2. Split−Supply Range: ±1.0 Vdc to ±18 Vdc

3. Very Low Current Drain Independent of Supply Voltage: 0.4 mA

4. Low Input Bias Current: 25 nA

5. Low Input Offset Current: 5.0 nA

6.Low Input Offset Voltage: 5.0 mV (max) LM293/393

LM2903N属于集成电路（IC） > 比较器。安森美半导体公司制造生产的LM2903N比较器逻辑比较器系列产品用于根据以数字格式表示的信息比较结果来生成输出；身份型比较器指示两个输入是否相同，幅度型比较器还指示两个输入不相同时哪个较大。它们不同于比较两个模拟输入幅度的器件，后者称为线性比较器且单独分类。
