• AD5662 Vout

    Please teach me about AD5662.

    Vout=Vref * (D/65,536)

    In this value, what gain is output buffer amplifier?

    I think that the gain=2  when Vfb pin is connected with Vout pin.

    Which is the output in that case 　0- Vref or 0-2Vref ?

    Thank you.

  • AD5662 starting sequence

    I am new to AD5662. I would like to know the sequence to start the data transfer. I used 0x280001, 0x30000f,then followed by data transfer of 0x00(Data) for channel A, etc. But it seems it works sometimes and not the other time. Can someone help to let…

  • EVAL-AD5662/AD5660/AD5640/AD5620

    Hi everyone!

    I'm using EVAL-AD5662/AD5660/AD5640/AD5620 and have AD5660 as my DAC and I noticed that there are grounding problems to the AGND and DGND pins of the evaluation board. It is said in the datasheet of the evaluation board that the analog GND…

  • AD5662: Output Buffer does not reach the Rails at nanoDac and add additional FSR Erroro - related to ALL nano Dacs with Voltage Output Buffer

    Q 

    The Output buffer of the AD5662 is specified Output Voltage Range in the
    datasheet (Rev A 12_2010) from 0 to Vdd. In my single Supply System (Vdd=5V) I
    cannot reach the GND (all "0") nor the Vdd (all "1") loaded into the DAC.…

  • Vdd2(Secondary side) question for ADuM1300 CN0064

    Dear Sir /Madam,

    Question-1

    Can we use your ADR02 as VDD2 of ADuM1300 due CN0064 reference circuit?

    Our customer choiced your ADuM1300 and AD5324,so he is studying now about VDD2.

    Your CN0064 show to use ADR02 Vref as power device.

    Dear AD Support Team,

    I am planning to design complex impedance analyzer, where I will excite the system using sine wave and by sweeping frequency. I found that AD5930 is great product to do this project. My start frequency may start somewhere near micro…

  • RE: nanoDAC-What are nanoDACs?

    nanoDACs are a portfolio of products which combine small package, low power and low cost digital to analog conversion.

    nanoDACs are monotonic DACs which can be powered off a single 3V or 5V supply and are available in the industries smallest packages…

  • nanoDAC - Which DACs should be used for open loop systems and which DACs should be used in closed loop systems?

    It must be stressed that depending on the application performance requirements, all nanoDACs can be used in both open and closed loop systems.

    In an open loop application the DAC drives the load (a valve or an actuator, for example) directly while in…

  • EVAL-AD5660: Source code of the included GUI and firmware

    Hi all,

    I am currently evaluating EVAL-AD5660 and i am getting erroneous output in the GUI reading of the voltage. At full scale, I am getting a 2.75V reading but the device should only have a 2.5V full scale reading. (Vref = 1.249V).

    I have checked…
