Part Number: DAC38RF83

Hi team,

In the DAC38RF83 datasheet, it states that the SPI clock rate is 10MHz. Can we run this faster? is there a maximum clock speed available for the SPI channel?

Thanks,

Hi AH,

TI recommends keeping the SCLK within 100ns period, 10MHz rate

Hi Kang,

Hope all is well! Do you think it would be possible to run faster at 40-50 MHz without degradation? Do we have any characterization data on running the SCLK faster?

Thanks,

AH

Hi AH,

sorry. We simply cannot recommend this as there may be register read/write errors when SPI bus is running at faster rate.
