PCIe-7846

Description

The NI PCIe-7846 (Part Number: 786456-01) is a high-performance multifunction reconfigurable I/O device, offering a sampling rate of 500 kS/s for data acquisition. It features 8 analog input channels and 8 analog output channels, along with 48 digital I/O channels, making it versatile for a wide range of applications. This device is powered directly by the PCIe bus, eliminating the need for an external power supply.

The analog input channels can operate in different modes—DIFF, RSE, or NRSE—that are software-selectable, providing flexibility for various signal requirements. These channels boast a 16-bit resolution with an impressively quick 2 µs conversion time. Similarly, the analog output channels offer a 16-bit resolution and an ultra-fast 1 µs update time, with a maximum update rate of 1 MS/s.

For digital-to-analog conversion, the NI PCIe-7846 utilizes an enhanced R-2R DAC. At its core, the device is powered by a Kintex-7 160T FPGA, which provides ample resources including 202,800 flip-flops, 101,400 LUTs, and 11,700 kbits of embedded block RAM. This FPGA is instrumental in handling complex processing tasks and enables reconfigurability for custom applications. Additionally, the device supports 16 DMA channels, facilitating efficient data transfers that are crucial for high-speed data acquisition tasks.
