ABSTRACT:
A D/A conversion system with a compensation circuit comprises a D/A converter for converting a digital input signal into an analog signal and a memory for storing a compensation data used for the compensation of the output of the D/A converter at an address corresponding to the digital input signal. The digital input signal is applied to the D/A converter and a signal corresponding to the digital input signal is applied to the memory. The output of the D/A converter is adjusted on the basis of the compensation data read out from the memory.
