FIELD: radio engineering, communication.
SUBSTANCE: differential amplifier with a zero level of output static voltages has a first (1) and a second (2) input transistor, a first (5) and a second (6) output bipolar transistor, a first (7) reference current source, a first (8-9) group of antiphase current outputs (8) and (9) of the device, a second group (10, 11) of antiphase current outputs (10) and (11) of the device.
EFFECT: enabling conversion of input signals which vary relative to the power supply common bus to output voltages having constant component levels close to zero and also varying antiphase relative to the power supply common bus.
