    Description ä ä ä ä The PCI-AOB8/12 (16/12) are full-size cards that can be installed in any long PCI slot of PC-AT class computers. They contain either eight or sixteen double-buffered digital-to-analog converters (DACs) that provide independent analog output channels of 12-bit resolution. Each analog output channel can be configured for ranges of: 0V to +2.5V...
  • Page 28 The DAC outputs are undefined at power-up. Therefore, in order to prevent excessive outputs to external circuits, the PCI-AOB8/12 (16/12) contains automatic circuits that set D/A outputs to less than 15 percent of span at system power-on. Upon power-up, the card is not in the Simultaneous Update mode.
