  • DAC8801: DAC Output when Clock is disabled, but SDI and CS is active

    Resolved
    Part Number: DAC8801 What will the DAC output do if the Clock input is not transitioning, but SDI and CS are moving as if the clock is moving. We have a circuit that when the system detects a system condition, it disables the clock by setting it low…

  • DAC8801

    Resolved
    Hi in order to reduce power consumption in our system we want to switch the DAC on and off prior to use. What is the wake up time of the DAC? Daniel

  • Positive voltage with DAC8801 and 1 amp op

    TI Thinks Resolved
    Other Parts Discussed in Thread: DAC8801 , DAC8550 Hello. In previous work, I have held the topology of the image, but with different DAC (as the AD755), for positive voltages without any problem. It seems an easy, simple that does not require many components…

  • DAC8801 POR threshold and register data retention

    Resolved
    Other Parts Discussed in Thread: DAC8801 I am trying to characterize some power up/down behavior we are experiencing with in an application using the DAC8801. Upon a power cycle, approximately 1-2 sec powered down, sometimes the DAC retains it's last issued…

  • DAC8811EVM-PDK: The /CS pin of J2 not output.

    Resolved
    Part Number: DAC8811EVM-PDK Other Parts Discussed in Thread: DXP , DAC8801 , DAC8811EVM Hi team, The /CS pin of J2 is always low output. Instead, I'll see the FSX pin output like output the /CE pin. Is it a configuration issue? Sincerely. Kengo.

  • DAC8411: DAC8411

    Resolved
    Part Number: DAC8411 Other Parts Discussed in Thread: DAC8801 , I was testing a DAC8801 using the DAC8801 Eval board. The SPI signals are coming from ports on an STM32F407 and are all about 3.3V signals. The DAC8801 worked very well, but we decided we needed…

  • RE: Need low offset error DAC

    Hi Kevin, I'm looking at unbuffered DACs per your advice. DAC8801 current output looked good at first glance, but then it looks like the full-scale accuracy is only 20%. Strange that its specified 20% only on the first page though, nothing about it…

  • RE: OPA189: Spike occurs when it as a I-V conversion OP after DAC8811 current output

    Hi Cindy, section 8.3.1 of datasheet of DAC8801 recommends the add of a compensation capacitor (C1). This cap would provide a phase lead compensation and by this decrease the ringing. Decreasing R8 to 47R and leaving C3 at 470pF can additionally destabilize…

  • RE: Load Independent 5mA constant current source (Load Resistance 650 ohm to 750 ohm).

    Resolved
    Hello Rajesh, There are a few different approaches you can take here. First is a dc REF, as described in this App Note: www.ti.com/.../litabsmultiplefilelist.tsp . Next is a currentDAC, such as: www.ti.com/.../dac8801 . And third, since you are employing…

  • Re: SPICE (or other) models for data converters

    Hi Rick, I know this thread has grown a bit stale, but I just found it searching and wanted to chime in my interest as well. Right now we're working on a new design, part of which uses R-2R MDACs (the DAC8801 / DAC8803 specifically) in a digitally-controlled…
