This device features 16 differential analog inputs or 32 single-ended inputs, offering a resolution of 16 bits. It can achieve a maximum sampling rate of 1.25 MS\/s for single-channel configurations and 1.00 MS\/s for multichannel setups. The input voltage range is DC coupled with options including ±0.1 V, ±0.2 V, ±0.5 V, ±1 V, ±2 V, ±5 V, and ±10 V, while maintaining a common-mode rejection ratio (CMRR) of 100 dB to minimize noise interference. On the output side, the PCIe-6353 supports four 16-bit analog output channels, with a maximum update rate of 2.86 MS\/s for a single channel, or 1.25 MS\/s when all channels are active. The timing accuracy of these output channels is specified at 50 ppm of the sample rate, alongside a resolution of 10 ns, all while operating within a voltage range of ±10 V and ±5 V.\u003c\/p\u003e\n\n\u003cp\u003eAdditionally, the device includes 48 programmable digital I\/O channels. Channel 0 is designated for waveform generation with a maximum sample size of 32 bits; it features an output FIFO capable of holding 2,047 samples and an input FIFO for 255 samples. The sample clock frequency ranges from 0 to 10 MHz depending on system and bus activity, while the USB clock frequency covers 0 to 1 MHz under similar conditions. The PCIe-6353 operates at a recommended voltage of 2.2 to 5.25 volts for input high, and 0 to 0.8 volts for input low. Furthermore, it integrates four 32-bit counters\/timers that enable functions such as edge counting, pulse measurement, and period calculations. Input channels for the counters include Gate, Source, HW Arm, Aux, A, B, Z, Up_Down, and Sample Clock.\u003c\/p\u003e\n\n\u003cp\u003eThe device dimensions are 9.9 × 16.8 cm (3.9 × 6.6 inches), and it weighs 169 g (5.9 oz). This multifunction I\/O device exemplifies robust functionality tailored for diverse industrial automation applications.\u003c\/p\u003e","brand":"National Instruments","offers":[{"title":"Default Title","offer_id":46683845918956,"sku":"781049-01","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_c1063813-bf6d-4a16-9d16-df6c196f9922.jpg?v=1753243110","url":"https:\/\/www.industrialautomationco.com\/products\/national-instruments-781049-01","provider":"Industrial Automation Co.","version":"1.0","type":"link"}
