ABSTRACT:
A digital/analog converter circuit (1) comprises a precompensation stage (10), a PCM/PWM converter stage (7) and a digital/analog converter stage (8), these components being arranged in the signal path in the stated order. The transfer function of the precompensation stage (10) is designed such that the analog output signal (19) is essentially proportional to the digital PCM input signal (11).
