AD7606C-16 || Digital Data to Voltage Conversion

Category: Hardware
Product Number: AD7606C-16

Hi Team,

I am using AD7606C-16 ADC IC for my receiver system.  I want to validate the ADC-received samples to my scope waveform. I am doubting what should I consider the value of Full Scale Range in the calculation formula.

Please Note: I haven't made any configuration changes for the ADC IC. 

Conversion formula:

Voltage= (Digital Data)* Full Scale Range / ((2^16)-1)

In the Oscilloscope I am seeing Vpp (measured at P wrt N I/p of ADC) is ~3.0Vpp

I am attaching the Digital Data, Pls suggest are the samples Ok. What Should I consider the Full Scale Range for my calculation?
CONVST Freq: 108KHz
Input Frequency: 27KHz

    So, after step 6, what are you doing next? do you perform more read operations and what do you get back on DOUTA? Can you send scope shots of this 6 steps plus several more read frames?

    Are you issuing CNVST pulses in between in order to trigger new conversion?

    Regards,
