National Instruments 779973-01 Multifunction I/O Device
National Instruments part number 779973-01 is an identifying part number for the USB-6225 Multifunction I/O Device. This device offers high accuracy and fast sampling rates. It features 80 analog input channels that can operate as either 80 single-ended channels or 40 differential channels. The NI 779973-01 provides 16-bit ADC resolution and a maximum sample rate of 250 kS/s per channel, which remains consistent even when using multiple channels simultaneously. The input channels' timing accuracy is within 50 parts per million of the sample rate. It is recommended to allow the device a warm-up time of 30 minutes before use, and it should be calibrated at least once a year for optimal performance.
The NI 779973-01 Multifunction I/O Device features two analog output channels, each offering 16-bit DAC resolution with 16-bit monotonicity. The maximum update rate for one output channel is 833 kS/s, and for both channels together, it is 740 kS/s. Similarly to the input, the output channels' timing accuracy is within 50 parts per million of the sample rate. The 779973-01supports an output range of ±10 V with an output impedance of 0.2 Ω. It includes overdrive protection for outputs up to ±25 Volts, ensuring robust performance and safety in varying operational conditions.
This device offers various input ranges, including ±0.2V, ±1V, ±5V, and ±10V. The maximum working voltage for analog inputs is ±11V. It features an input FIFO size capable of holding 4,095 samples. The 779973-01 provides overvoltage protection for all analog input channels and sense channels. During overvoltage conditions, the input current is limited to a maximum of ±20 mA, ensuring protection against electrical faults or excessive input voltages.
