Low-cost A/D & D/A

Low-cost PC/104 A/D and D/A modules operate from -40 Cto +85 C yet don't require calibration

  • Multifunction Analog and Digital I/O modules
  • Standard configuration:16-bit A/D, 12-bit D/A, 48-lines of digital I/O
  • Software programmable interrupt configuration
  • No adjustment potentiometers or calibration needed
  • Free software drivers in C, Windows, and Linux
  • 90 mm x 96 mm expansion boards for industrial, medical, security, transportation, and Mil/COTS applications
  • Based upon Linear Technologies' precision converters and voltage references, these cards do not require calibration which results in quick, easy setup; plus it eliminates the necessity for readjustment and recalibration to installed units in the field
  • The input ranges for the PCM-MIO-G-AD-1 are 0-5V, 5V, 0-10V and 10 volts
  • Two independent, 16-bit A/D converters support up to 16 single-ended or 8 differential channels or various combinations of both
  • The conversion speed is 100K samples/sec
  • The PCM-MIO-G-DA-1 has eight independent, 12-bit D/A converters on board
  • The output voltage ranges are 0-5V, 0-10V, 5V, and 10V
  • All output channels are programmable and can be updated and cleared individually or simultaneously
  • Both the PCM-MIO-G-AD-1 and PCM-MIO-G-DA-1 boards have 48 lines of digital I/O individually programmable for input, output, or output with read-back
  • The lines are TTL-compatible and can sink 12 mA which supports direct connection to industry-standard, optically isolated AC and DC signal conditioners
  • Isolated signal conditioners protect, filter, and isolate the analog input and output signals from electrical transients
