I used LTC6242 as a voltage follower configuration: - power to IC is 4.2V

- measured V+ to IC is 3.8V

- V- is feedback to Vout, measured about 3.6V

- output is set at high impedance for testing

(Note that I wanted output to be 3.8V)

When the power is…

    我利用LTC6242来搭建3阶有源滤波器，系统上设计的电源方案为正负5V，所以购买的LTC6242HVIDHC，但是这个芯片出现电压超过7V时候电流上升。根本不能达到10V，和器件手册标称有出入。

    我的电路如下，现在加了正电压和负电压，超过7V左右就异常，请用过这个器件的朋友能回答我，我用错在哪儿。
