(1) Current drawn by the LabJack through the USB. The status LED is responsible for 4-5 mA of this
current.
(2) Self-powered would apply to USB hubs with a power supply, all known desktop computer USB
hosts, and some notebook computer USB hosts. Bus-powered would apply to USB hubs without a
power supply and some notebook computer USB hosts.
(3) This is the total current that can be sourced by +5V, analog outputs, and digital outputs.
(4) The input current at each analog input is a function of the voltage at that input (Vin) with respect to
ground and can be calculated as: (8.181*Vin - 11.67) μA.
(5) Single-ended burst mode only returns even binary codes, and thus has a net resolution of 11 bits.
In addition, extra noise in burst mode can reduce the effective resolution.
(6) Maximum analog output voltage is equal to the supply voltage at no load.
(7) Must also consider current due to 1 MΩ resistor to ground.
(8) The IO lines each have a 1500 ohm series resistor.
(9) These lines have no series resistor. It is up to the user to make sure the maximum voltages and
currents are not exceeded.
(10) CNT is a Schmitt Trigger input.
