• LTC6242 voltage follower output saturation voltage

    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…

  • Help with tunable Fc ADI reference circuit

    Hello,

    I am trying to tweak this example circuit - https://www.analog.com/en/technical-articles/a-simple-digitally-tunable-active-rc-filter.html

    I have an input channel range of 0-3.3V and could use adjustable Fc for my low pass filters and this looks…

  • High pass filter tunable

    I'm looking for High pass filter tunable and I can see this component 'LTC6912-2' that you can change the cutoff frequency by the SPI bus. Do you know how it works exactly ? After searching I found this document but I don't know how it works exactly.…

  • 关于LTC6242HVIDHC供电范围问题

        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。

  • RE: High voltage fully differential amplifier ( supply voltage >= +/- 30V )

    Hello Homan,

    Thanks a lot for the solution. I'll certainly try out the second circuit which looks easy with minimal components. 

    Could you please take a look at the attached datasheet of LTC6244, page 21? 

    It explains FDA from single ended opamps. I'm…
