National Instruments 782916-01 Multifunction Reconfigurable I/O Device

The National Instruments 782916-01 (USB-7856R) Multifunction Reconfigurable I/O device is a highly adaptable system designed for a wide range of applications. It features a user-programmable Kintex-7 160T FPGA for onboard processing that provides flexibility for both analog and digital I/O operations. The device can be configured using NI LabVIEW and the LabVIEW FPGA Module that allows users to create customized hardware solutions. This device is compatible with USB 2.0 and supports data transfers via DMA, interrupts, or programmed I/O.

The analog input section includes 8 channels configurable in DIFF, NRSE, or RSE modes. The input resolution is 16 bits with a maximum sampling rate of 1 MS/s per channel. It is ideal for precise and fast data acquisition. The device employs a successive approximation register (SAR) ADC for accurate signal conversion. Input ranges are selectable between ± 1 V, ± 2 V, ± 5 V, and ± 10 V. Overvoltage protection of ± 42 V ensures durability during power fluctuations. The device offers a high input impedance and protection features.

The 782916-01 device analog output capabilities include 8 single-ended channels with a 16-bit resolution and a maximum update rate of 1 MS/s. The output voltage range is ± 10 V that makes the device suitable for applications that require precise voltage control. Overvoltage and short circuit protection are built into the outputs. Settling times and glitch energy at midscale transitions are minimized for improved signal integrity.

The NI 782916-01 device digital I/O section features 48 reconfigurable channels with maximum frequencies of 80 MHz and 10 MHz depending on the connector used. The device supports various logic families with user-selectable voltage levels to interface with different systems. Each channel is protected against voltage surges and the power-on state can be customized per line. The FPGA offers significant resources including 202,800 flip-flops and 101,400 LUTs.

Power requirements for this multifunction reconfigurable device range from 9 V to 30 V with a maximum power consumption of 20 W. The device offers overvoltage protection up to 40 V. It has a compact design and weighs 1,000 g. It is designed to withstand high humidity levels and has an altitude rating of up to 2,000 meters.
