mended on the analog outputs. The required ca-
pacitor value is defined by:
C
Example:
A value of 680 pF may be used with only 1.45%
error which is negligible.

Combined Digital and Analog Filter Response
switched-capacitor filter, digital filter, and off-
chip single pole RC-filter at 2 Fs, is shown in
Figures 9, 10, 11, and 12. The overall response
is clock dependent and will scale with Fs. Note
that the response plots have been normalized to
Fs and can be de-normalized by multiplying the
X-axis scale by Fs.
