PS398/PS399
Precision 8-Ch, Diff. 4-Ch, 17V Analog Multiplexers
The table below shows how many time constants (m
τ) are
needed to reach an accuracy of one LSB.

Now, let’s calculate what the maximum sampling rate for the
PS398. Assume a 12-bit accuracy and room temperature
operation.

or fS = 630kHz.
Assuming a x4 oversampling rate, the maximum sampling speed
for the PS398 would be 630
