• Tying DGND to VSS on AD5252

    Hi,

    I am planning to use the AD5252 and AD5254 on a programmable filter and interface the components using I2C with an Arduino Nano. The filter supplies are bipolar VDD=+2.5V,VSS=-2.5V.

    I was hoping to use the same supplies to power the Arduino by setting…

  • AD5252, reset I2C communication, not using power restart

    Hi,

    In case I2C communication of AD5252 meet some problem, for example, noise intefer a command which is transmitted, thus both of sender and receiver are waiting for each other, can we reset only I2C communication, led by AD5252, not using power restart…

  • Digital Potentiometer with asymmetrical supply

    Hi,

    is it possible to run the AD5252 with an asymmetrical supply, e.g. +3.3V and -1.5V?

    Best regards,
