Part Number: TLV320ADC6140

Hi team,

Could you give me the typical and Minimum SNR value at input impedance = 10kohm, DRE disabled, Gain 0dB?

    Hi Shinji,

    We don't provide min/max specs for SNR at other impedance settings as this is not part of the test program, but generally there is a 1-2dB degradation in SNR moving to 10kOhm and another 1-2dB using 20kOhm. This is more noticeable if the DRE is used, but if it is not then the degradation between 2.5kOhm and 20kOhm is only about 2dB total.

    I hope this helps!

    Best,

    Zak
