OUTPUT SELECTOR CONTROL
Any analogue PGA channel can be routed to any analogue output. Care should be taken to ensure
that each analogue output is routed to only one analogue input – it is not possible to route multiple
inputs to one output through the output selector. All analogue outputs can be independently enabled
and disabled. Additionally, all outputs can be tri-stated to allow the output to be connected to
applications where ports can either be inputs or outputs.
Note: It is recommended to mute the PGAs before changing the output selector to avoid pop/click
noises when selecting a different output source.
