National Instruments 778317-01 Dynamic Signal Acquisition Device

Part Number 778317-01 is the identifying part number for the National Instruments PCI-4452 Dynamic Signal Acquisition Device. The 778317-01 features 4 simultaneously sampled, true differential analog input channels having a resolution of 16 bits. It features a Delta-sigma ADC with 128-times oversampling. The device has sample rates ranging from 5 kS/s to 204. 8 kS/s in increments of 190.735 µS/s. Likewise, it features a FIFO of buffer size of 512 samples. Furthermore, the data transfers in the device take place through DMA, programmed I/O, or interrupts.  

The 778317-01 also features 8 digital I/O channels that are compatible with TTL/CMOS standards. Inputs of 0.0 V to 0.8 V are considered input low while those from 2.0 V to 5.0 V are considered input high voltage. Likewise, outputs up to 0.4 V are considered to output low voltage while voltages from 4.35 V are considered to output high voltage. The power-on state for these channels is input (high-impedance) and data transfers in this channel take place through programmed I/O. 

The 778317-01 also has 2 up/down counter/timers and 1 frequency scaler. The resolution of counters/timers is 24 bits while the resolution of the frequency scaler is 4 bits. The channel is compatible with TTL/CMOS standards. Likewise, the base clocks for counters/timers and frequency scaler are 20 MHz, 100 kHz, and 10 MHz, 100 kHz respectively. Data transfers in these channels take place through DMA, interrupts, or programmed I/O and it supports the scatter-gather DMA mode.  

The 778317-01 measures (4.19 by 12.28 by 0.73in.) in physical dimensions when connectors are not included. It uses a 68-pin VHDCI female-type connector for analog I/O and a 50-pin VHDCI female-type connector for digital I/O. The module is recommended for operation between 0 °C to +40 °C at a relative humidity of 10% to 95% and can be stored in between −25 °C to +85 °C. The module has a calibration interval of 1 year.
