ADC128S102: Clock Frequency ADC128S102_SMD

Part Number: ADC128S102

Tool/software:

Hello good morning.

I have some queries related to the ADC128S102_SMD. We currently use it with our product and we have to make some modifications for a new project.

The queries are the following:
1. The datasheet says that the recommended clock frequency is between 8Mhz and 16Mhz. What consequences can lowering this frequency to 2Mhz or 4Mhz have? Can it cause the ADC converter to malfunction or will it work well?
2. Do you recommend any ADC converter to operate between 2Mhz and 4Mhz clock frequency?

Thank you very much and have a good day.

  • Hi David,

    The recommended clock frequency will actually be from 0.8 to 16MHz. The 8MHz minimum under the electrical characteristics is due to a formatting issue. Everything will work as expected with a clock frequency in this range. 

    Regards,
