Part Number: ADS8912B
Hi,
Let me ask you following basic questions about AC accuracy.
Q1) According to the datasheet, SINAD and SFDR specifications are as below.
SINAD : 102.5dB(typ)
SFDR : 125dB(typ)
I do not understand why SFDR is better than SINAD(125dB>102.5dB).
Will you teach me the reason?
Q2) Fig21 (datashhet 16page)
There describes that SNR is 102.8db.
I think that as the noise level is around -150dB, SNR should to be around 150dB...
Will you teach me why SNR is 102.8dB from Fig21?
Thank you for your kindness.
Best Regards,
