Forum Post: RE: DAC38J82: DAC38J82IAAV
Hi, Are you following the SPI timing diagram in the datasheet? I've not seen this issue from any other design in of this device, so it's most likely your spi controller is not configured or operating...

Dear Alexander, thanks for your quick response. The first document you send is something we encountered. We have FPGA sin3filter demodulator and send clock from FPGA and receive data at FPGA. But we...

Just adding some info: When data error occur power on secondary side=3.48V and after LDO=3.21V and its the same voltage levels as in correct data operation. Shorting...
View ArticleForum Post: RE: ADC084S021: I want to know spi mode of this
HI Jeffery, You're correct, it is SPI Mode 3. CPOL = 1 as SCLK idles high while CS is inactive, and CPHA = 1 as data is clocked in on the trailing (rising) edge of SCLK. Regards, Joel
View ArticleForum Post: RE: DAC8571: Convert 0 to 2.5 VDc to 0 to 60 mV
Hi Nimit, DACs divide down a reference voltage based on the input code. The DAC8571 is a 16-bit DAC, so assuming you use a 2.5V reference the output step size is 38uV. What output range do you need,...

View ArticleForum Post: RE: DAC8830: DAC8830 Additional Settling Time information
Hi Evan, DAC8830 is an unbuffered DAC. The settling time is dominated by the output buffer you select. The settling time we give in the datasheet is really just the time the DAC takes to rise/fall to...

Hi Tomas, Applying the clock before low side (VDD2) power up violates the absolute maximum ratings of the device. Is this what you mean by secondary side?
