Input capacitors C
1 to C5 are only required for ac
input signals; dc input signals do not require these
components.
The gain of the uncommitted stage (3) is set by
external components employed around the input and
output pins (see Specification page).
Application Recommendations
To avoid noise and instability the following practices
are recommended:
(a) Use a clean, well-regulated power supply.
(b) Keep tracks short.
(c) Inputs and outputs should be shielded wherever
possible.
(d) Analogue tracks should not run parallel to digital
tracks.
(e) A “Ground Plane” connected to V
SSwill assist in
eliminating external pick-up on the channel input
and output pins.
(f) Avoid running high level outputs adjacent to low
level inputs.
(g) The serial clock should not be running
consecutively when not in the process of actually
loading data.
