The National Instruments USB-6003 is a versatile Multifunction I/O Device, ideal for both portable applications and efficient data logging. It features eight single-ended analog input channels that can be reconfigured to four differential channels, catering to various user requirements. The device is equipped with two 16-bit DAC analog outputs and includes a total of 13 Digital I/O lines—eight from Port 0, four from Port 1, and one from Port 2—ensuring extensive flexibility in connectivity. The I/O connections are facilitated by a USB Micro-B receptacle, designed for USB full-speed bus operation at 12 Mb/s.

The USB-6003 provides robust protection for test systems, integrating overcurrent protection of 200 mA and overvoltage protection of ±20 V. It operates with a +5 V output voltage at ±3% and supplies a maximum current of 150 mA, with a short-circuit current of 50 mA. The device offers excellent sample accuracy with a timebase accuracy of ±100 ppm and a frequency of 80 MHz, ensuring precise sampling rates for analog input and output at 100 kS/s.

With a compact design, the USB-6003 measures 93.2 mm × 86.2 mm × 23.6 mm (3.67 in. × 3.40 in. × 0.93 in.) when equipped with screw terminal plugs and weighs 105 g (3.70 oz).
