LM2903 双比较器能接正负双电源么

请问LM2903 双比较器能接正负双电源么 ？看规格书，只标明最大VCC电压36V。

手册中未见到负电压的设计，不建议使用负电源供电。比较器可以看作是一个1位的ADC，仅仅完成一个判断高低的功能，要么0，要么1，一般不用在负电压的场合

多谢。我改用2904运放来当做比较器用吧。

今天又看了下LM2903的规格书（第一页描述中）有这么一段话，好像是说也可以工作在双电源下，只要两个电源差值在36V以内就行了。

These devices consist of two independent voltage
comparators that are designed to operate from a
single power supply over a wide range of voltages.
Operation from dual supplies also is possible as
long as the difference between the two supplies is
2 V to 36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage.

也可以双电源供电的哈。数据手册中第一页就有描述：Single-Supply or Dual Supplies

亲；可以双电源工作。且双电源工作时的性能会更好些。注意＋－电源电压和不要超过36V即可。
