{"product_id":"national-instruments-778999-01","title":"National Instruments 778999-01","description":"\u003cp\u003eThe National Instruments part number 778999-01 designates the PXI-6722 PXI Analog Output Module, a high-performance device designed for a variety of applications including signal generation, control systems, and automated testing. This module supports eight voltage output channels, featuring a double-buffered digital-to-analog converter (DAC) that ensures smooth and continuous output. With a maximum update rate of 476 kS\/s utilizing local FIFO and up to 182 kS\/s through host PC memory, the PXI-6722 facilitates high-speed data transfer for dynamic applications. Its 2047-sample FIFO buffer allows for efficient handling of large datasets while preserving data integrity. The module incorporates three DMA channels and supports multiple data transfer methods, including DMA, interrupts, and programmed I\/O, enabling enhanced data manipulation. The scatter-gather DMA mode further optimizes data transfer processes. \u003c\/p\u003e\n\n\u003cp\u003eFor precision operation, the PXI-6722 provides a voltage output range of +10 V, featuring DC output coupling and a low output impedance of 0.1 Ω, capable of driving a maximum current of +5 mA, which guarantees output stability even with passive loads. Protective features, such as short-circuit protection to ground, are included to prevent damage. The module is equipped with support for digital triggering from PXI trigger lines with a minimum pulse width of 10 ns, compatible with 5 V TTL logic. The power requirements for the module include +3.3 VDC at 300 mA and +5 VDC at 1.5 A typical, with a maximum of 3 A. The PXI-6722 measures 16 cm × 10 cm (6.3 in. × 3.9 in.) and utilizes a 68-pin VHDCI connector. It operates optimally in ambient temperatures ranging from 0 to 55 degrees Celsius, with a storage temperature range of -20 to 70 degrees Celsius and relative humidity from 5% to 90% RH, non-condensing. The module is suitable for installation at altitudes up to 2000 meters and adheres to a pollution degree of 2, making it a reliable choice for demanding industrial environments.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683816886508,"sku":"778999-01","price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0217\/1112\/6600\/files\/National_Instruments_Group_Photo_-_Final_Compressed_aea76cd3-2834-40cc-935c-dcb267ff2b66.jpg?v=1753243036","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-778999-01","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
