Description
The USB-6281 Mass Termination device is available under multiple part numbers including 780054-01, 780054-07, 780053-04, 780053-01, and 780054-04. This device features 16 single-ended or 8 differential analog input channels with an ADC resolution of 18-bits. When operating on a single channel, it can achieve a sample rate of up to 625 kS/s maximum, and for multiple channels, it can reach up to 500 kS/s maximum.
For safety, it provides overvoltage protection of ±25 V when the device is on and ±15 V when the device is off. During overvoltage conditions, the input current is limited to ±25 mA maximum per AI pin. Additionally, the device maintains an input bias current of ±100 pA.
In terms of output capabilities, the USB-6281 Mass Termination device offers 2 analog output channels with a DAC resolution of 16-bits. The output update rate for one channel can reach up to 2.86 MS/s maximum, and for both channels, it can achieve 2.00 MS/s per channel maximum. Lastly, it has a timing accuracy of 50 ppm, ensuring precise performance across its functionalities.
