TLV320ADC6140：Inquiry about electrical characteristics

user6504452

Part Number: TLV320ADC6140


Dear ADC6140-Team,

1.I would like to know the SNR, DR, and THD for an input impedance of 10kΩ and 20kΩ using the conditions in the picture below.

 2.The chip has an AC-coupled input range typ value of 2Vrms, and what are the maximum and minimum values?such as those caused by individual differences or temperature differences.

Thanks and best regards,

you
