National Instruments 779418-01 Multifunction I/O Device

National Instruments part number 779418-01 is the version of the PCI-6221 Multifunction I/O Device that has a 37-Pin D-SUB Connector. This versatile connector ensures a strong connection that allows the device to transmit a range of signal types, making it an excellent choice for various testing applications. One of the standout features of the 779418-01 is its analog input capabilities. With 16 single-ended and 8 differential analog input channels, the 779418-01 boasts a DNL that guarantees no missing codes- resulting in excellent analog-to-digital converter output.

The analog input channels of the 779418-01 feature a high-resolution ADC of 16 bits, as well as a FIFO size of 4,095 samples. Both the single channel and multichannel analog input options of the device have a maximum sample rate of 250 kS/s. 

The 779418-01 also comes ready with 2 analog output channels, which have a DAC resolution of 16 bits. Unlike the consistent rate of the analog input channels, the maximum update rate for the analog output channels varies depending on how many channels are being used. This means that 1 analog output channel has a maximum update rate of 833 kS/s, while the maximum rate for 2 analog output channels is 740 kS/s a channel. The size of the analog output FIFO is 8,191 samples, and it is shared among all of the channels that are used. The timing accuracy of the analog output channels is 50 ppm of the sample rate, while the timing resolution is 50 ns.

Designed for full functionality in a wide range of conditions, the 779418-01 can operate in a temperature range from 0 ºC to 55 ºC (32 ºF to 131 ºF), and it can be safely stored in temperatures ranging from -20 ºC to 70 ºC (-4 ºF to 158 ºF). This compact multifunction I/O device measures 10.6 cm × 15.5 cm (4.2 in. × 6.1 in.), and weighs only 95 g (3.3 oz). It is recommended to calibrate the 779418-01 annually to ensure both accuracy and reliability.
