Fig.3 SINAD vs Input Level – Typical Values
Application Notes
Application Recommendations
(f)
Analogue tracks should not run parallel to digital
tracks.
(g)
A "Ground Plane" connected to V
SS will assist
in
eliminating external pick-up on the channel input and
output pins.
(h)
Do not run high-level output tracks close to low-
level input tracks.
(i) Input signal amplitudes should be applied with due
regard to Figure 3.
(a)
A noisy or badly regulated power supply can
cause instability and/or variance of selected gains.
(b)
Care should be taken on the design and layout of
the printed circuit board.
(c)
All external components (Figure 2) should be
kept close to the FX009A package.
(d)
Inputs and outputs should be screened wherever
possible.
(e)
Tracks should be kept short.
To avoid excess noise and instability in the final installation it is recommended that the following points be noted.

Notes
(1) Channel Amplifiers 1 to 8 are inverting amplifiers.
(2) Analogue input capacitors C
1 to C8 are only required for a.c.
input signals, d.c. input signals do not require these
components.
