## **Introduction** USB-4702 and USB-4704 are low-cost USB data acquisition modules that can be installed without opening the chassis; simply plug in the modules to access collected data. Reliable and rugged enough for industrial applications, yet sufficiently affordable for home systems, USB-4702 and USB-4704 DAQ modules provide an easy and efficient means of adding measurement and control capabilities to USB-capable computers. Additionally, because USB-4702 and USB-4704 draw power from the computer via the USB port, no external power connection is required, making these modules the most cost-effective solution for testing and measurement applications. ## **Specifications** ## Analog Input **Channels** 8 single ended/4 differential (software programmable) **Resolution** USB-4702: single ended: 11 bits Differential: 12 bits USB-4704: single ended: 13 bits Differential: 14 bits **Max. Sampling Rate** USB-4702: 10 kS/s max. USB-4704: 48 kS/s max. Note: The sampling rate of each channel is influenced by the number of used channels. For example, if 4 channels are used, the sampling rate will be 10k/4 = 2.5 kS/s per channel. - **FIFO Size** 512 samples - **Overvoltage Protection** 30 Vp-p - **Input Impedance** 127 k Ω **Sampling Modes** Software, onboard programmable pacer, and external - **Input Range and Absolute Accuracy** |**Single Ended**|**Single Ended**|±10|N/A|N/A|N/A|N/A|N/A|N/A|N/A|N/A| |---|---|---|---|---|---|---|---|---|---|---| |**Differential**||N/A|±1|±1.25|±2|±2.5|±4|±5|±10|±20| |**Absolute**
