• RE: LTC2312-12 Rising edge timing of CONV & SCK


    Thank you for your answer. I would like to know what kind of problems to LTC2312-12 in this case. Is there a possibility to change a something unexpected mode as LTC2312-12?

    Thanks & Regards,


  • RE: LTC2312-12 SDO MSB No toggle

    The LTC2312-12 maximum conversion rate is 500ksps. You would need to use the LTC2313-12 if you wanted to run at 2.5Msps.

  • RE: LTC2312-12 Exiting Nap Mode

    If the LTC2312 is already in NAP mode before the first CONV pulse shown, the rising edge of SCK will wake the part and the second CONV pulse will start a conversion. The time between the rising edge of SCK and the rising edge of CONV should be at least…

  • RE: LTC2312-12, the SDO is always Hi-Z?

    One possibility is that during power on, CONV has at least two positive edges while SCK has no positive edges. This would place the ADC into NAP mode forcing SDO into a Hi-Z condition until a positive edge occurs on SCK. If four positive CONV edges occur…
