A transformerless floating output circuit is provided by driving two load terminals from amplifying means having differential current outputs. A differential amplifier connected across the load terminals provides a feedback signal which is compared with the input signal to provide a control signal for the amplifying means. The feedback connection regulates the control signal so that the differential currents produce a load voltage matching the input voltage, irrespective of the value of the load impedance and whether or not one load terminal is tied to a fixed potential, such as ground.
