The PCCDAC 08 is an eight-channel, analog output card for PCs equipped with Type II PC Card slots. The heart of the board is an octal, 13-bit digital-to-analog converter of which 12 bits are used for each output. Analog voltage signals are generated by the D/A from registers. Control of I/O operations is done by the Field Programmable Gate Array (FPGA) on the card. Double-buffering of the output registers permit simultaneous output updates.
Range of the analog outputs is bipolar, ±5V.
In addition to the analog outputs, there are eight bi-directional digital I/O lines arranged in two, 4-bit ports. They provide the capability of sensing and controlling discrete events (via external signal-conditioning hardware). These ports can be programmed to be either eight inputs, eight outputs, or four inputs and four outputs. |
