Features (NI 6722/6723)
The NI 6722/6723 are Plug-and-Play, analog output (AO), digital I/O (DIO), and timing I/O (TIO) devices for PCI bus computers. The NI 6722
features:
• eight AO channels with 13-bit resolution
• eight lines of TTL-compatible DIO
• two 24-bit counter/timers for TIO
• a 68-pin AO I/O connector
The NI 6723 features:
• 32 AO channels with 13-bit resolution
• eight lines of TTL-compatible DIO
• two 24-bit counter/timers for TIO
• a 68-pin extended AO I/O connector
Because the NI 6722/6723 have no DIP switches, jumpers, or potentiometers, they are easily software-configured and calibrated. For the NI 6722/6723 connector pinouts, refer to Chapter 2, I/O Connector.

6722/6723) The NI 6722 has eight channels of voltage output at the I/O connectors, and the NI 6723 has 32 channels of voltage output at the I/O connectors. The reference for the AO circuitry is internal. Each NI 6722/6723 voltage output channel has a bipolar range of ±10 V from AO GND. You cannot select an external reference to adjust the AO voltage range.
