• Daisychain AD5262 how many chip in series?

    Hi,

    AD5262 needs 9 bit to communicate, the question is: does 2 chip in daisychain will need 18 bits? How many AD5262 I could chains?

    Thx Michele

  • RE: AD5262 -DIGIPOT CONFIGURATION

    As datasheet says ad5260 need 8 bit word, ad5262 need 9 bit word. If you use ad5262 with 8 bits it will not execute your command probably. Bit bang 9 bits.

  • Disabling analog power DAC

    Hello, help me please! I use DAC AD1852 and digital potenciometer AD5262. I need to disable analog power these chips, but digital power is always enabled. Can it damage AD1852 or AD5262?

  • RE: AD5262 daisy chain

    Based on Figure 52 in DS, the correct sequence is U2(A0 = 0 or 1) --> U1(A0 = 0 or 1) . Only 18 bits data input from SDI is allowed in one SPI write transaction for AD5262.  Only the 18 MSB bits will be taken and others will be ignored, if more than…

  • Regarding Digi-Pot AD5262

    Hi all,

         We are using a AD9837 + AD5262 to generate a Sine Waveform with desired frequency and amplitude. Data is written to both the IC's  by  the same SPI from the 8051 Controller.

          We are getting the proper response from the AD9837...Whatever frequency…

  • I have a question on using potentiometer

    Hi, I'm Digital team manager on VPIX MEDICAL.

    As I said on title, I have a question on using potentiometer(AD5262).

    There is a pin called 'SDO' and we don't need to read data.

    So, is it okay to NC(no-connect) on this pin?

    Thank you…

  • RE: AD5260/5262 Vlogic power supply

    Hi Hiroshi-san,

    "The logic supply voltage should always be less than or equal to VDD" should also apply to AD5260 / AD5262, since there is an internal diode between logic supply pin and Vdd pin. Hope that answers your query.

     

    Cheers,

  • 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…
