a 55 Ω characteristic trace impedance. Route all RIO Mezzanine Cards
with a similar impedance to ensure the best signal quality. Refer to 3.3 V
Digital I/O on 50-Pin IDC Connector in the Specifications section for the
logic levels.
Integrated Analog Input
This section applies only to the following NI sbRIO devices:
Each NI sbRIO-9623/9633 devices has 16 multiplexed, 0–5 V, single-ended,
12-bit analog input (AI) channels. Each NI sbRIO-9626/9636 device has
16 multiplexed, ±10 V, single-ended or eight differential, 16-bit AI channels.
Connector J503, the MIO connector, provides connections for analog inputs,
outputs, and grounds. Refer to Figure 17 for a pinout of connector J503.
The following figure shows the circuitry for one AI channel on the
NI sbRIO-9623/9633.
