DA4

4 (High Voltage) D/A Outputs (±100 VDC)

The Digital-to-Analog (D/A) module DA4 provides 4 high-voltage independent D/A output channels with a maximum full-scale range of ±100 VDC at ±10 mA (max). Linearity/accuracy is ±0.15% FS range over temperature. The DA4 provides voltage control loop mode, which is programmable for the application.

The DA4 module includes extensive Background Built-in-Test (BIT). In addition to output signal read-back (wrap) capabilities, overloaded outputs are detected with automatic channel shut-down protection, and the results are displayed in a status word. DA4 also include D/A FIFO buffering for greater control of the output voltage and signal data. Once enabled and triggered, the D/A FIFO buffer accepts, stores, and outputs the voltage commands for applications requiring simulation of waveform generation (single or periodic). The output data command word is formatted as a percentage of the Full Scale (FS) range selection, which allows maximum resolution and accuracy at lower voltage ranges.
