The page below refers to previous versions of the Open Ephys headstage. The headstage that currently ships with an Open Ephys Starter kit is Intan part #C3324, http://intantech.com/RHD_headstages.html?tabSelect=RHD32ch&yPos=0
The Open Ephys headstage uses an Intan amplifier chip to filter, amplify, and multiplex 32 channels of neural data. An analog-to-digital converter inside the chip digitizes each signal with 16-bit resolution. Instead of one wire per channel, as is required for analog headstages, our headstage can send 32 channels over a cable with only 12 wires. And the signal is purely digital, so there are no artifacts from tether movement.
