• AD5161: Error in equation 4 / effect of wiper resistance, VW

    I am wondering how the wiper resistance influences the output voltage of a
    digital potentiometer in voltage divider. In the AD5161 datasheet, there is
    equation (4) on page 16 where Vw depends on Rwiper. Is this equation correct
    (except the Raw…

  • AD5161 : Will the chip will reset if we switching from I2C to SPI ?

    We have tried two methods.

    1.written the wiper register by i2c and switched it in to spi mode and read through i2c and getting wiper as zero.

    2.written wiper by spi and made the chip in to I2C mode and and read by i2c also getting wiper reg as zero.

  • Can AD5161 readback R value in SPI mode?

    Can the AD5161 read back the programmed R value in SPI mode via the SDO pin or is this only intended for daisy chain operation?

  • AD5161 Digi-Pot I2C Bus timing

    Hi All,

    My customer is considering to use AD5161 Digi-Pot for his new design.

    Prior to the design work, he sent me a confirmation of I2C bus timing specification of AD5161 in its Data Sheet.

    Page 5 of the Data Sheet says the Data Hold Time (t6) is…

  • AD8295 to AD7690 Reference Design Problem

    I recently built the reference design included with the AD8295 datasheet, which uses the AD8295 to differentially drive an AD7690 ADC chip.  This is a very compact implementation but I can't seem to get it to work correctly.

    That said, I notice that…
