Digital-to-Analog Modules

Digital to Analog (D/A) modules convert digital electrical signals to an analog signal. NAI offers for D/A smart function modules offering from four (high voltage) to sixteen output channels. The DAx smart function modules 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 (and/or current) commands for applications requiring simulation of waveform generation (single or periodic).

COSA® Design Advantages

As a result of our Configurable Open Systems Architecture™ (COSA®), NAI’s I/O Boards can be configured in a virtually unlimited number of ways.

Select from over 70 pre-integrated I/O, measurement, simulation or communication functions to meet your application-specific requirements quickly, and without the need for custom boards or NRE charges.
