LJTick VRef2.5V

LJTick VRef2.5V

The LJTick-VRef is a Voltage reference accessory that outputs a stable 2.5V signal. These ticks are commonly used as an excitation voltage for various circuits. Designed for use with the Labjack U3, U6, UE9, T4 and T7 data acquisition modules they are simply plugged into the screw terminals. The IOA and IOB lines are pass-through terminals, and do not interact with the accessory in any way.

VRef-25 Specifications:

  • Voltage: 2.5V
  • Accuracy: ±0.08%, ±2mV
  • Maximum load: 50mA
  • Short circuit current: 100mA
  • Temperature coefficient: 5ppm/°C

The VRef-25 uses the voltage reference chip: LT1461CIS8-2.5#. The VRef-41 uses the voltage reference chip: LT1461CIS8-4#.

LJTick-VRef-25 Screw Terminal Descriptions

2.500: This screw terminal outputs the 2.5V reference voltage.

GND: Same as LabJack ground (GND).

IOA/IOB: These lines are directly passed through from the screw terminals they are connected to.
