• AD5541A output range

    Hello,

    I'd like to supply 5.00 V to both Vref and Vdd on a AD5541A DAC. According to the datasheet, this is ok.  It's convenient because the DAC's current draw is low and it will save a voltage regulator.  What will the output voltage range…

  • EVAL-AD5541A/42ASDZ connection issue

    Hello,

    I have bought EVAL-AD5541A/42ASDZ and find out cannot connect to computer to evaluate.

    Is that EVAL-SDP-CB1Z is the missing part i needed to order?

    Do EVAL-SDP-CB1Z come with a necessary cable that i can connect to U10 of EVAL-AD5541A/42ASDZ…

  • AD5541A, LDAC and POR state,

    Hello,

    I have few questions related to AD5541A

    In AD5541A datasheet is stated that POR will reset DAC register to zero, but not SPI register.

    1. In case LDAC is permanently tied to GND, the output is guaranteed to be zero at power up?

    2. What is the POR…

  • AD5541A glitches every 512 codes

    The AD5541A on our board is producing noise glitches at 512-code intervals.  To be specific, when stepped in increments of 32 DAC codes, starting at mid range (0x8000), we see noise glitches every 16 increments (e.g., at 0x8200, 0x8400, etc.).  I might…

  • 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…

  • Which reference should be used with the AD5541A/42A?

    Which reference should I choose to get the best performance from the AD5541A/42A?

  • .BIN file for CN0348 (AD5541A eval) EEPROM (24LC32A)

    I have a CN0348 eval board that mates with SDP-B board but isn't connecting.  I've discovered my EEPROM (24LC32A) is blank and need to load the data on the EEPROM to get the SDP-B board to connect to the daughter board.  Can anyone supply me with…

  • AD5541A的参考电压输入端电阻问题

    手册中说AD5541A的基准电压输入电阻最小值为9KΩ,是不是意味着参考端施加2.5V的电压时,基准电压输入端会有最大2500/9000=0.28mA的输入电流?所以下面参考电路才加了一个AD8628的跟随器?

    如果是这样的话这款DA芯片算起来总的消耗电流还要加上参考端的电流?芯片IDD的电流最大才150uA,参考端电流比IDD还要大了,这也不是严格意义上的微功耗了啊。

  • Where do I tie the exposed paddle on DACs such as the AD5541A, AD5542A, AD5512A, AD5668, AD5628, AD5669 and AD5629 that are packaged in LFCSP?

  • AD5541A中英文数据手册中输出噪声频谱密度的条件不一致

    输出噪声频谱密度这项参数,中英文文档第4页中,都标注的是11.8nV每根号Hz,但条件“DAC code”却不一致,英文中条件为0x0000,中文手册中是0x8400,请问以哪个为准?
