FIELD: radio engineering, communication.
SUBSTANCE: digital-to-analogue converter includes a weight current switching unit (1), the current output (2) of which is connected to a reference resistor (3), a parasitic capacitor (4) connected to the current output (2) of the weight current switching unit (1). In order to improve operating speed, the current output (2) of the weight current switching unit (1) is connected to the input of a non-inverting voltage amplifier (5) and the current output (6) of a non-inverting current amplifier (7), wherein a frequency correction element (9) is connected between the output of the non-inverting voltage amplifier (5) and the current input (8) of the non-inverting current amplifier (7).
EFFECT: shorter time for setting output voltage of a digital-to-analogue converter.
