A few questions about the glitch impulse and update of the DAC.
In the datasheet (https://www.analog.com/media/en/technical-documentation/data-sheets/AD5781.pdf) in figure 43-45 the glitch impulses are shown when an RC low-pass filter is used. However, the value or R and C is not given as I can see.
What is the R and C values on the filter?
In figure 45, Cx referees to what capacitor? Where is it located?
In figure 48, where should the output clamp be located and look like?
In our application LDACn is hardwired low and the SPI interface is used to load/output values. In the case the same data is written to the DAC, will the DAC still update the registers and generate the glitch impulse, or only when the data is new from previous state?
