• AD5260/5262 Vlogic power supply

    Hi all.

    I have a question about Vlogic power supply.
    Question : Does VL need to be always less than VDD?

    Our customer are using VDD=5V, VL=5V nomaly. but sometime VL > VDD.


    In D/S of AD5260 ”ABSOLUTE MAXIMUM RATINGS”

         VL to GND   0 V to +7 V

  • AD5260 在5v下工作正常,在12v下工作不正常

    我搭了个数字电位器电路,期望使用Ad5260 数字电位器输出0v到12v的电压,我控制用的MCU的 gpio端口电压是3.3v的,vdd和A端输入电压为12v时不工作,改为5v时工作正常,难道SPI通信端口也要用12v电平?

  • AD5260/AD5262: gain and frequency show poor performance

    I am struggling trying to think out a solution to design a transimpedance amplifier (TIA) which can convert 100 nA to 10 mA. This is 5 decades. I want to be able to amplify these to 1.5V minimum. (3V max).

    I want to do most of the amplification in the…

  • AD5262 daisy chain

    Hi

    Please show me how to use daisy chain of AD5262.

    In data sheet, the discription is only AD5260 single digi-pot.

     

    I think a procedure for writing is

    1. U2(A0=0)

    2. U2(A0=1)

    3. U1(A0=0)

    4. U1(A0=1)

     

    Is this correct ?

     

    Best regards,

    wada…

  • RE: Power-up/down Sequence Timing in Digital Potentiometers and Analog Switches

    Actually AD5260 and ADG1414 do have a VL input.

    Besides, if I read the datasheets correctly, the ESD protection diodes could be forward biased if I supply any voltage higher than the conduction value of such diodes in the wrong order.

    Also, even if…
