TL071H: How to use it as a voltage follower if the IN+ voltage may be larger than the V+ voltage

jian sun
Part Number: TL071H

Please help to check the schematic.

I wish to use TL071H as a voltage follower. It's important that the IN+ voltage may be larger than the V+ voltage, Is it OK?

    您好，

    这里是中文论坛，您可以使用中文发帖。

    查看 TL071H的绝对最大额定值表格，其输入端信号范围是(VCC–) – 0.5 ~  (VCC+) + 0.5，即最大到V+ +0.5V，如果大于这个范围，很可能会永久性损坏芯片。

    如果想使用TL071H，只能降低输入电压值，否则只能考虑选择其他符合要求的运放。
