Abstract
An apparatus converts a digital value including “a” bits into an analog signal and has 2 D/A converters. Here, b is an integer number that is greater than 0. Each of the D/A converters is designed to convert a digital value having “a−b” bits. The digital value that is supplied (for i=1 . . . 2 ) to the ith D/A converter for the purpose of D/A conversion corresponds to the “a−b” most significant bits in the sum of the digital value that will be converted by the apparatus and to i−1. The output signal for the apparatus is the mean value for the output signals from the D/A converters. Such an apparatus can be produced such that it can be accommodated easily and efficiently on a semiconductor chip and, irrespective of the details of protocol implementation, permits a completely linear conversion of the digital value being converted into an analog signal.
