(5) External power supply specifications
The power supply (+5V) for the card-size analog I/O must be supplied from an external source.
Prepare a power supply (stabilized power supply) that satisfies the following conditions for each
card.
+5V power supply
Output voltage
Ripple and noise
Output current
(6) Others
When designing the connector PCB for the card-size analog I/O, refer to sections 5.3.1 to 5.3.6 for
the other required items.
