• RE: DAC Output noise

    Hi-

    I moved this question related to the AD5660 to the Precision DACs community.  Someone here should be able to assist.

  • AD5620 Model Options

    i have a question about AD5620 Model Options.

    what difference between AD5620A..., AD5620B... and AD5620C...? Difference is only in relative accuracy between models (A the best?)

    next, AD5620-2-3 parts include an internal, 2.5 V, 5 ppm/°C reference,…

  • RE: 3V/5V Precision DACs - Which internal reference should I use?

    I am presently working on a cct which has a Ad5660-1 nanodac on it.

    This device is powered from 3V and the vrefout is 1.25V. AD5660-1

    The Vout is 2xVrefout or 2.5V.

    I have noticed a peculiar problem.

    Whilst power cycleing the pcb and during other…

  • RE: looking for reference circuit of AD9834 to op amp

    Hi Miguel,

    The specifics of some of the parameters are still to be determined but the supply voltage and output range would be about 20V, max current output could be about 100ma, Not sure about the impedance.  It would need high amplitude resolution so…

  • RE: AD9834 - Constant Mclk/2 (37.5MHz) output

    Thanks for the quick response. Were right, the output of Mclk/2 (37.5MHz) was due to SPI mode.

    I was using SPI mode 1 (CPOL=0 – CPHA=1). I changed to SPI mode 2 (CPOL=1 – CPHA=0).

    I attached capture of low speed (1MS/s) logic analyzer.

    In this…

  • RE: Single supplier digital controlled current source ?

    Hi Patrick,

    I apologize for the delayed reply. I have two options for you, both will work in a single supply configuration.

    Given the resolution that you want of 100nA, it would definitely not be advisable to use the circuit in figure 3 of CN-0151…

  • 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…
