• Electrical Characteristics of LTC2312-12


    I don't understand what Absolute Input Range in LTC2312-12 data sheet as follows mean. Please let me know.



  • LTC2312-12 Output signal issue


    Our customer has an issue about output signal of LTC2312-12. Could you please support me?

    The customer has used LTC2312-12 in their products. The output signal of TC2312-12 is fixed to Hi level or low level approximately one out of dozens of…

  • 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.

  • LTC2312-12 CONV pin pull-up/down


    Can we add 1k ohms or 10k ohms pull-up or pull-down resistor to CONV pin? Are there any problems to LTC2312-12 in that case?

    Best regards,


  • 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,


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


    Our customer give us the question why the SDO output is always Hi-Z regardless of the signal level of CONV after power on.
    According to the data sheet page10 of LTC2312-12, the SDO output is always forced into the high impedance state while CONV is…

  • LTC2312-12 Exiting Nap Mode


    I have a question about SCK timing for exiting NAP mode. According to the datasheet, we should send a pulse on SCK showing Fig.8 on the datasheet.

    Can I exiting NAP mode if I send the pulse like a following timing?

    Best regards,


  • RE: LTC2312 Internal Reference - Long-Term Stability


    There is no long term stability data available for the LTC2312 internal reference. If this is important to you I would recommend using a different ADC that supports using an external reference with specified long term stability. An example would be…

  • How to set LTC2312 Using the External Reference?

    I can not find how to set LTC2312 Using the External Reference in datasheet, and find  By default, REF is an output pin and produces a reference voltage VREF of either 2.048V or 4.096V depending on VDD.
