A DIGITAL-TO-ANALOG CONVERTER CIRCUIT, A METHOD FOR OPERATING THE SAME, AN APPARATUS AND A METHOD FOR CONTROLLING A DIGITAL-TO-ANALOG CONVERTER CELL

摘要

A digital-to-analog converter circuit is provided. The digital-to-analog converter circuit includes one or more digital-to-analog converter cells. A first digital-to-analog converter cell includes a first transistor which is configured to be switched to a conductive state when the first digital-to-analog converter cell is activated. A first terminal of the first transistor is coupled to a defined potential, wherein a second terminal of the first transistor is coupled to a common output node of the one or more digital-to-analog converter cells. The digital-to-analog converter circuit further includes a voltage protection circuit coupled between the common output node of the one or more digital-to-analog converter cells and an output node of the digital-to-analog converter circuit to regulate a voltage between the common output node and the defined potential.
