Abstract
An integrated D/A converter has a first feedback circuit for generating a first bias voltage to compensate for systemic changes. A second feedback circuit includes a plurality of switchable current sources biased by the first bias voltage and controlled by an externally supplied attenuation control signal to generate a second bias voltage which is applied to control the D/A current sources.
