single-ended or Isolated unbalanced differential amplifier
l Also referred to as unbalanced, isolated or unbalanced differential
amplifier
l None
of the inputs are connected to ground for safety and to avoid ground
loops
l Typically used in isolated DAQ systems
l Often identified by the use of a single PLASTIC (isolated) BNC
connector
l Used in GEN DAQ ISOLATED Basic amp
l Can perform DIFFERENTIAL MEASUREMENTS with different limitations
and options, compared to a differential grounded amplifier.
