USB-4704 48 kS/s, 14-bit, 8-ch Multifunction USB Module

Analog Input

• • Channels: 8 single ended/4 differential (software programmable)
  • Resolution: USB-4704: single ended: 13 bits

Differential: 14 bits

• • Max. Sampling Rate: 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.
