Abstract

The invention relates to electronic and radio engineering and can be used as an audio frequency amplifier. The technical result is an increase in current-voltage conversion accuracy and the elimination of dynamic and intermodulation distortion. A single-ended amplifier with a digital input comprises a digital receiver, a preliminary converter in the form of a digital input code to output current converter, an input pulse transformer, a voltage follower containing two controllable current sources, a control current adjuster, two emitter followers, and direct current power terminals, wherein the supply voltages are interrelated by given relationships. A digital-to-analog converter (DAC) of the amplifier is designed to be capable of converting digital code at the input to current at the output, and comprises power terminals, the supply voltages being interrelated by given relationships, a current follower, and a load resistor. A voltage follower of the amplifier comprises a first and a second controllable current source, two emitter followers, two control current adjusters, two control resistors, and power terminals.
