The PCI-DDA08/12 from Measurement Computing is an accurate and powerful measurement instrument that plugs into any PCI slot in your computer. Combined with powerful software, it turns your personal computer into a measurement system that may be used to automate experiments, construct product test stands, monitor and control production equipment or be embedded in products such as airport security systems and jet fighter test simulators.

The PCI-DDA08/12 is completely plug-and-play. There are no switches, jumpers or potentiometers on the board. All board addresses, interrupt channels etc. are set by your computer's plug-and-play software. Even calibration is performed via software by using on-board trim D/A converters.

Analog Outputs: The PCI-DDA08/12 provides two channels of 12-bit analog output (one part in 4096). Each channel is implemented with an independant D/A converter and the analog outputs are updated under software control. Software selectable output ranges of 0-10V, 0-5V, 0-2.5V, ±10V, ±5V, and ±2.5V are provided and channels may be set at different ranges. The D/A outputs provide rated accuracy to ±5 mA, are short circuit protected (25 mA limit) and are cleared to 0 volts on power up or reset.

The table below details the input ranges and resolutions for the available input configurations and gains.

 
Bipolar Range Resolution Unipolar Range Resolution
±10V 4.88 mV 0 - 10V 2.44 mV
±5V 2.44 mV 0 - 5V 1.22 mV
±2.5V 1.22 mV 0-2.5V 0.61 mV
 
Parallel Digital I/O: The PCI-DDA08/12 provide 48 bits of parallel, digital I/O in the form of four 8-bit ports and four 4-bit ports. This digital capability is based on an on-board, high output current emulation of the 82C55 mode 0 and allows each of the ports to be set independently as input or output. On power up or reset, the ports default to the input state (high impedance). The digital I/O section of the board is fully connector compatible with all of Measurement Computing's 50-Pin digital signal conditioning boards.
