How much current can x3SR headstage deliver?
The x3SR includes constant current stimulators that can deliver currents ranging from 10 nA to 2.55 mA over an 14 V compliance. Please be mindful the deliverable current is highly dependent on electrode impedance.
If you need to exceed 14V compliance (i.e. needing to deliver more current due to high impedance), x3SR can support a 18V compliance at the expense of reduced life time. According to Intan Technology, at the higher compliance, "each stimulator circuit begins to fail after many stimulation pulses, typically in the range of 30,000 to 1 million stimulation pulses. After degradation, the positive current output will be too low, often zero. This is a permanent hardware failure that cannot be reset by power-cycling the device."
