ADS6445: Serial interface acknowledge signal

Malkangouda Patil
Prodigy 70 points
Part Number: ADS6445

Tool/software:

Hi, 

1. Can anyone tell me after configuring the serial registers on the ADC does the master receive any acknowledge signal back?.

I did not find it neither on the timing diagram nor anywhere in the datasheet. If this facility isn't there can you guide me on how to generate the acknowledge signal after the ADC is configured.

2. What is the signaling standard for the serial interface, could you point me out to its DC characteristics?

Thank you 

Regards

    Hi Malkangouda,

    SPI is not the same as I2C, there is no acknowledgement. SPI signaling standards can vary from part to part and vendor to vendor, as there is no standard.

    The SPI interface timing and voltage levels for the ADS6445 are given in the datasheet.

    Regards,
