Multichannel D/A converter

摘要

There are provided 2n-number of data latches (2), 2n-number of dynamic range setting latches (7) and 2n-number of output dynamic range change circuits (8) in correspondence to 2n-number of D/A converters. Controlled by the outputs of AND gates (4), the respective dynamic range setting latches (7) output dynamic range setting data DR to the corresponding output dynamic range change circuits (8). The output dynamic range change circuits (8) change dynamic ranges for the analog outputs of the corresponding D/A converters (5) as a function of the dynamic range setting data DR to output the changed analog outputs from corresponding output terminals (26). This enables the dynamic ranges for the plurality of D/A converters to be set individually without the provision of further external terminals.
