Notes:
1. Analog input capacitors C1 to C5 are only required for a.c. input signals; d.c. input signals do not
require these components.

4. Application
4.1 Recommendations
To avoid noise and instability the following practices are recommended:
1. Use a clean, well-regulated power supply.
2. Keep leads short.
3. Inputs and outputs should be shielded wherever possible.
4. Analog tracks should not run parallel to digital tracks.
5. A “Ground Plane” connected to Vss will assist in eliminating external pick-up on the channel input and
output pins.
6. Avoid running High Level Outputs adjacent to Low Level Inputs.
