(1) Current drawn by the LabJack through the USB. The status LED is responsible for 4-5 mA of this current.
(6) Maximum analog output voltage is equal to the supply voltage at no load.
(7) The IO lines each have a 1500 ohm series resistor.
(9) CNT is a Schmitt Trigger input.
(8) These lines have no series resistor. It is up to the user to make sure the maximum voltages and currents are not exceeded.
(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)
µ
A.
(5) Single-ended burst mode only returns even binary codes, and thus has a net resolution of 11 bits.
