DS210x D/A Boards

Fast D/A conversion

Many control applications require D/A conversion to provide the control signals for the actuators. The DS210x D/A boards provide various channel numbers, resolutions, and speeds for you to choose from.  

  • D/A boards with various resolutions, channel numbers, and speeds
  • Up to 32 channels, resolution up to 16 bits
  • Minimum settling time of 1.6 μs

Application Areas

D/A conversion is required by many rapid control prototyping applications to provide the control signal for actuators. In the other direction, in hardware-in-the-loop applications, sensors that provide analog signals have to be simulated.

Key Benefits

The D/A boards provide various channel numbers, resolutions, and speeds for you to choose from. The following table gives you an initial overview. All three boards can be configured from Simulink® with Real-Time Interface. You can select the voltage range for each channel individually.

Board Channels Resolution Sample Time 1)
DS2101 D/A Board 5 out 12 bit 3.0 μs
DS2102 High-Resolution D/A Board 6 out 16 bit 1.6 μs
DS2103 Multi-Channel D/A Board 32 out 14 bit 10.0 μs

1) Speed and timing specifications describe the capabilities of the hardware components and circuits of dSPACE products. Depending on the software complexity, the attainable overall performance can deviate significantly from the hardware specification.
