• RE: 4x LTC2662 - in daisy chain

    I think you need to use the write and update command,0011.  When you use the write command, it only writes to the output register, the output won't be updated until you do an update command.  write to n and update channel n will write and update the…

  • LTC2672 vs LTC2662

    At first glance, the 16bit versions of the LTC2662 and the LTC2672 appear to be identical.
    What are the differences? 

    Thx, Beat

  • Multiple LTC2662 devices on SPI bus

    Is it possible to use multiple LTC2662 devices in a single SPI bus using Regular SPI mode ( as shown below), rather than in Daisy Chain mode?

  • RE: LTC2662 - Troubleshooting

    Are you sending data in 8 bit chunks or in 24 bit chunks?  If you are using 8 bit chunks you are programming the part incorrectly. Every time chip select comes high the part is programmed.  So 8 bits are shifted in and that command is executed, then 8 more…

  • LTC2662-16 Oscillating current draw and software showing warnings

    Hi everyone, I am just starting to work with the LTC2662-12 along with the DC590B. When connecting the chip to a power supply and opening up the ltc2662 software, after a moment the power supply begins periodically (~1 second) showing the chip drawing…

  • Using Jupyter Notebooks to interface with LTC2662 & DC590B

    Hi everyone, 

    A similar question was asked previously, but unfortunately the answer wasn't too helpful. I would like to use Python 3 via Jupyter Notebooks to control an LTC2662 board. Would this be something I can do with the ACE Software? If not, is …

  • Demo board DC2692A with DC590 - using my own software to drive LTC2662

     I need to use my own program and not QuickEval, is there command set for DC590 SPI to control the LTC2662 on the demo board DC2692A.

    While all drivers are loaded as part of QuickEval, there is no documented command set for your own program.


  • LTC2662 questions


    I'm using LTC2662, but I think It is not working.

    My problem is the dac always return open circuit flag, when I write data ( actually next step )

    In my initial code, I just set config reg all 0, span 25mA . After that I write data through uart…

  • LTC2662 question?

    Dear Sirs,

    Q1.The LTC2662 has 5 current sources. If I only use 4, can another VDD not be connected?

    Q2.Is the VDD supply voltage operating at 3.3V and the current output to 300mA?

    Q3.Can VDD and VCC be connected to the same voltage?

    Q4.If the VDD supply…

  • LTC2662 FAQ

    Q1: Can the outputs be connected together to sum the currents?

    A1: Yes, any or all of the outputs can be connected together to increase the current output.  Since the outputs are current sources no additional circuitry, like a resistor, is require to sum…
