• AD5142 - IBIS File

    The IBIS model provided on our website (www.analog.com/ad5142) is designed only
    for LFCSP package.
    Could you please provided an IBIS file for DSO package – 16 ld TSSOP?

     

    LFCSP and TSSOP have same pinout, you can use the same IBIS file…
  • Troubles with AD5142

    Hi! I cann't control AD5142 with stm32f4 by SPI. I connect AD5142 like rheostat in feedback of op amp (for amplifing). Scheme in attach. But when I send some data via SPI to AD5142 it don't answer and Vout isn't change. For change resistance, I send b0001000000000001…

  • AD5142 life expectancy

    I want to make a regulator circuit that regulates a voltages via a mcu(SPI). I want as high update rate as possible.

    What would the life expectancy of the AD5142 be, if I update each resistance once every 1ms?

    Best Regards Kristian Solberg

  • AD5142 maximum current

    Hello

        I'm a starter on using AD5142 and notice the maximum current of Ia Iw Ib is just 6mA, does that mean if I connect W to Vdd and A to GND, then program code to reduce Rwa, the chip will get permanent damaged?(Vdd=5V, single power supply, Vss=GND…

  • AD5142 - SPI modes not consistent

    1.

    I have some weird behavior while talking to the AD5142 digital pot. I initialize the system (ATMEGA128) with CPHA=1 and CPOL=0, since a temperature sensor needs the CPHA activated and the AD5142 then needs CPOL=0 as per the datasheet.

    However the…

  • AD5142 SCLK Edge Rate

    Digital Potentiometer AD5142 datasheet calls out an edge rate of 1ns/V in note 1 under (Interface Timing Specifications) in reference to the input signal used in test. Is there an edge rate or rise/fall time requirement for the SCLK pin?

  • AD5142 Power supply sequence

    Hi ADI team. My customer considering to use AD5142. In DATAsheet, the order of powering VA,VB,VC, and digital input, it is described as not important if after VSS,VDD and VLOGIC. Is it should wait how much time after VSS,VDD and VLOGIC? Please tell me…

  • RE: SPI Read protocol unclear for AD5142

    I have finally figured this out. The issue is that the clock speed was too high for the open-drain SDO with pullup (2.2k) to handle. I simply slowed my clock down from 20 to 1 MHz, which luckily is OK for my application, and the 16-bit standard SPI protocol…

  • Controlling digital potentiometer (AD5142) by Arduino UNO

    Hi, I am trying to control digital potentiometer (AD5142) by Arduino UNO.


    Here is the pin configuration of AD5142.

    I connect SCLK pin to 13 pin of Arduino (serial clock pin), SDI pin to 11 pin of Arduino (MOSI pin) and SDO pin to 12 pin of Arduino …
