Please tell me why when loading an array of 16 numbers on the SPI interface in the range from 0 to 1000 at the DAC output signal non-uniformity of speed there. Who has experience in supporting chains and who faced such a case.
Is Vout on AD5451 datasheet figure 47 = Vref * D/2^10? Can Vref be small, i.e. ~5mV?
Hi Vladimir,
My understanding to your question is why does the DAC use current or voltages as outputs. The AD5451 is an IOUT DAC that uses an amplifier at the back-end to convert the current to voltage. Current is used because the part is designed to…
Through a resistor safer. It turns out that the DAC does not have a built-in resistor compared to the AD5451? I want a full range of the output voltage, it does not need to do divider. A resistor inserted between the face value chain Vdd and VREF?
In page 5 of AD5450/AD5451/AD5452/AD5453 data sheet, Timing Diagramis shown and looks like data is loaded into input shift register in MSB first manner.
in the serial interface example in page 21-22, looks like data is loaded in LSB first manner and when…
这个芯片(AD9833)的名字我猜的,可忽略看,如果是这个芯片,左看右看也不知是干吗呢?

If you are using or plan to use the AD5415 12-bit DAC chip in a daisy-chain configuration, you need to read page 20 of the marked up data sheet attached. If you are using the SDO output of even a single AD5415, then you also need to see the erratum marked…
