APPENDIX B. RECOMMENDATIONS FOR MAXIMUM PERFORMANCE
The following are some general recommendations for maximizing the performance of Cirrus Logic evalu-
ation systems.
– When applying power to the evaluation board, use power supplies isolated from utility AC line and
ground. Isolated power supplies typically inject less electrical noise than non-isolated power
supplies.
– Connecting Analog Inputs
1. Route power supply and communications cables away from analog input cables.
2. Keep all cable lengths as short as possible, especially the analog signal input cables.
3. Using twisted/shielded wire will reduce noise being induced onto the analog input cables.
