• AD5541 max output rate


    I have a question regarding the AD5541 maximum output value update.

    As far as I understand the main limiting parameters is the settling time.

    but I am not able to understand if the SPI interface is a bottleneck or not.

    In the datsheet is reported…

  • RE: what is the real output range of AD5541?

    hello, Ivan

    This issue resolved by changing the buffer, original one was saying a rail-rail output in its spec, but actually it can not be.

    Thanks for your support.


  • RE: set up ad5541 support for imx6sx SOM (device tree)

    echo 0.100000000 > out_voltage_scale

    I think you have too many zeros there.

    Try fewer; I am not sure that IIO supports 10(-9) scales.

    I think 10(-6) should work.

  • Handling LDAC for the AD5541 using the ad5446.c driver

    From looking at the Linux 4.15 kernel, it appears that the AD5541A DAC is controlled using the drivers/iio./dac/ad5446.c driver.  Looking through the source code, I see that I can handle the device using a standard SPI device.  What I don't see is any way…

  • LTspice model for AD5541


    I have been searching online but I could not find an LTspice model for the AD5541; does it exist?

  • What will happen with AD5541 if pull CS high before 16 bits data clocked in?

    As the tile, if I only clock in several bits (less than 16 bits) into the DAC, and pull CS high, what will happen? Will AD5541 abandon the data or just simply shift out several bits and appending the new ones, then load them into the DAC.

  • AD5541/2 AD5541A/2A noise specification

    I'm looking for a very low noise 16 bit DAC and the AD5541A and AD5542A stand out with a 0.1 - 10Hz noise specification of only 0.134uV p-p. After a  few moments of reflection though, this seems hardly credible given the noise spectral density is specified…

  • AD的技术专家们,我想知道AD5541数模转换器能够转换的信号带宽是多少,为什么芯片手册上没有,我用这款芯片10kHz的信号可以转换,而换成25kHz左右的信号却不能正常转换,这是怎么回事?


  • RE: Very low noise DAC

    Thanks for the reply.

    The AD5791 is 1.1uV i.e. much worse than AD5512
    The AD5541/AD5542 seem to also be a possible choice
