INA114 正负12V供电,最大共模输入电压是多少?

Other Parts Discussed in Thread: INA114, TPS5430

如题,INA114 正负12V供电,最大共模输入电压是多少? 要是用12V电压转换成-12V电压,用什么芯片比较好?

  • INA114 正负12V供电,最大共模输入电压是多少?

    输入电压在电源轨内,大概+-10V的样子可以正常放大,输入电压可以高于电源电压,虽然不会坏,但是放大器的放大功能失去了。

    要是用12V电压转换成-12V电压,用什么芯片比较好?

    可以使用TPS5430做成反压的buck-boost。
