National Instruments 779066-01 Multifunction I/O Device

National Instruments part number 779066-01 is the version of the PCI-6221 Multifunction I/O Device that has a 68-Pin VHDCI Connector. This high-density connector equips the 779066-01 for flexible and high-speed signal transmissions, making it a valuable part of any test setup. This multifunction I/O device features 8 differential or 16 single-ended analog input channels which each have an ADC resolution of 16 bits. A standout feature of the device’s analog input channels is the DNL, which ensures that no codes are missed. As a result, the 779066-01 produces top quality analog-to-digital converter output. 

With a DC input coupling, the analog input of the 779066-01 spans across a range of voltages including ±0.2, ±1, ±5, and ±10. While the device does not have a minimum sample rate, the maximum rate for both singular channels and multiple channels is 250 kS/s. The timing accuracy of the device is measured and maintained at 50 ppm of the sample rate, while the timing resolution is 50 ns. 

The 779066-01 also boasts 2 dedicated analog output channels, each with a DAC resolution of 16 bits. The analog output features a ±1 LSB DNL, measuring within one step of the ideal step count. In addition, a monotonicity of 16 bits is guaranteed with the 779066-01. The output range measures at ±10 V, and the maximum update rate for one channel is 833 kS/s. When two channels are used, the maximum update rate lowers to 740 kS/s per channel. Similar to the analog input timing, the timing accuracy and resolution for the analog output is 50 ppm of the sample rate and 50 ns respectively. 

The physical dimensions of the 779066-01 measure 10.6 cm × 15.5 cm (4.2 in x 6.1 in), and it weighs 92 g (3.25 oz).
