Hi Tsuji-san,
I would also like to add that the input impedance does actually vary with sample rate. For a typical curve of this, please refer to this thread: https://e2e.ti.com/support/audio/f/6/p/963547/3559654#3559654
Hi Collin,
Do you mean the worst case minimum is 60kohm -5% = 57kohm or
60kohm -20% = 48kohm?
Or worst case 48kohm, 1sigma distribution 57kohm?
regards,
Hello,
The number previously provided represent estimated standard distributions of a Guassian (normal) distribution. +/-20% deviations will be very uncommon as the probability calculations of these events would indicate.
1-sigma = +/-5%: 57kΩ - 63kΩ
4-sigma = +/-20%: 48kΩ - 72kΩ
