• 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.

  • RE: AD5662 starting sequence

    Hi ,

    I am not sure where you got those commands, as the first 6 bits of AD5662 are don't cares.

    To write to the DAC register, PD1:PD0 should be 0b00 then followed by the 16 bit data bits equivalent to the DAC output value desired. Let me know…

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

    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.…

    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…

  • What amplifier would you recommend for a low power  4mA to 20 mA  current loop transmitter application?

    For low power application that requires RRIO and greater than 5V supply, I would recommend the AD8657 due to its low supply current of 22 uA per amplifier. The AD8657 is a 18V, micropower, rail-to-rail RRIO amplifier optimized for low power and wide operating…

    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…
