PCM1821: Distortion of input impedance

Part Number: PCM1821

Hi team,

Typical value of input impedance is 10kHz as the datasheet.
Could you share the distribution or similar one?
Is the distortion changed by Fs?

Best regards,
koyo

  • Hi Koyo,

    I can't share the distribution but I can say with process variation you could expect the input impedance to vary between devices by up to +/-20%. The input impedance does not change with sample rate for this device.

    Best,

    Zak
