IP-AD8250D
IP 16 bit A/D converter, 8 A/D modules
The IP-AD8250D has eight 16-bit A/D converters that run simultaneously at 250Ksps with front-end buffers that are fault protected. The A/D converters support bipolar voltage inputs, and include ±5VDC or ±10VDC The A/D converters operate continuously at the selected sampling rate. Results are either stored in the FIFO or discarded when appropriate. Only selected channels are saved into the FIFO, so that depth per channel is proportional to number of channels saved. The customer may desire to think of the IP module as similar to a Digital Storage Oscilloscope (DSO). A DSO can store and display several waveforms and can record signals prior to the trigger. The trigger point is completely configurable by reprogramming the FIFO’s programmable empty flag. A/D samples are acquired and stored into the 18 bit FIFO when acquisition has been started. Once the pre-trigger data has been acquired, triggering becomes active. Further, acquisition before the trigger that are seen will result in the earliest data being discarded at the same time new data is saved, thus maintaining the most recent data in the FIFO. Once the trigger event is seen, no more data is discarded from the FIFO, and acquisition proceeds until the FIFO is full. At this point, the acquisition stops, and the HOST can read the data from the IP. Interrupts can be sent to the HOST at Event and at acquisition finished. If desired, such as for a continuous acquisition, data can be read from the FIFO while acquisition is in progress, for continuous streaming. Unfortunately, it will not be possible to maintain a high sampling rate in this scenario due to the time constraints of the IP interface
Applications: This is a perfect solution for:
-
Process control,
-
Industrial control, or
-
Precision instrumentation
Software Support:
The IP-AD8250D is supported under Windows NT /2000 by two sample programs, which are supplied with the IP in the board support package. Both examples are designed to work with an IP-type carrier from ALPHI, such as the PCI-4IPM. One sample program, called SnapShot, fully exercises the IP module in pre- and post-trigger modes, and displays the data to the screen. Data can be stored to a file and can be reloaded in the program at a later time. The second program, called DrawIpAdc, operates the IP in continuous mode, and displays the data to the screen. Full source to both HOST DSP code and the applications are provided.
