AO Channels

The NI ELVIS RIO CM MXP connectors A and B have two AO channels per connector, AO0 and AO1, which you can use to generate signals of 0 V to 5 V. Each channel has a dedicated digital-to-analog converter (DAC), which allows all AO channels to update simultaneously. The DACs for the AO channels are controlled by a serial communication bus from the FPGA. MXP connectors A and B share this bus and therefore, all channels must share the same update rate.

The following figure shows the AO topology of the NI ELVIS RIO CM.
