主题: LM393LV 中讨论的其他器件
您好、
我尝试使用单个 TLV1922 来检测两个 9V 块电池的欠压情况。
它们串联在一起、因此我将使用运算放大器减法电路来获取最高电池电压(以最大负电位为基准)。
现在、TLV1922 的措辞对我来说有点难理解。
When both IN- and IN+ are within the common mode voltage range:
If IN- is greater than IN+ and the offset voltage, the output is low.If IN- is less than IN+ and the offset voltage, the output is high.If IN- is equal to IN+, the output state is technically indeterminite and output state is determined by the random polarity of the internal offset votlage.
那么、有了 A 、这是否意味着输出有效并 被置为低电平 、或者反过来?

(+3.3V 以–9V 为基准、而不是以 GND 为基准)
谢谢!
