• RE: hii there, am using ad5263 digipot and after the programming i can't measure the resistance (both end to end and Raw / Rwb) through DMM. In other words it (DMM) shows some erroneous value which is continuously changing. Why that happens??

    Hi Karalan,

    We need more details regarding your setup for us to better understand the issue you are encountering.

    Can you provide the following information regarding your setup:

  • AD5203: Negative voltage at the output

    Is it possible to connect a negative voltage to any of the potentiometers
    outputs (A,B,AGND) in order to achieve a negative voltage at the wiper (W)? I
    need a voltage range from -5V to 0V. If it is possible, which output(s) have to
    be connected…

  • Digital Pot Configuration with 3.3V Host Device

    I am configuring AD5263 with 3.3V powered Spartan VI FPGA. Schematics as shown:

    Since Host device is 3.3V , Vlogic =3.3V (3v3 in schematics)

    DigiPot is used for Op-Amp Gain Adjustment and Op-Amp operating on ± 12V.

    Vdd = +12V

    Vss = -12V

    No of Op…

  • RE: using a Digipot in place of the drain resistor in a common source amplifier

    You have a C304 and C307 in the resistor path, probably for low pass filtering... If you replace R304, are you removing C304 as well?

    Can you share a simplified circuit ?

    Hi, Koushik

    I have a same question on new device AD5263...

    Is it okay to NC(no-connect) SDo pin?

  • RE: AD5593R different address between documentation and reality

    Hi Koushik,

    I have no oscilloscpoe available, but I did several test with other IC's to verify, if there is a problem with bus communication, shell commands or programming. All port-expander and adc (e.g. AD5263) test were succsessful. I did the test…

  • 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.
