Method for conversion of a value of an analog signal to a compressed digital word uses conversion of the analog signal to a linear digital word according to a successive approximation scheme. The process of conversion of the analog signal to the linear digital word is terminated by the compression module when all bits of the compression word have been already evaluated. Apparatus for conversion of a value of an analog signal to a compressed digital word a linear successive approximation analog-to-digital converter. The output of the linear digital word of this converter is connected to the input of the linear digital word of the compression module comprising a section number register, while complete conversion signal output of the compression module is connected to a complete conversion signal input of the linear analog-to-digital converter, and a bit ready signal output of the linear analog-to-digital converter is connected to a bit ready signal input of the compression module.
