Abstract
The A/D-converter with optional analog preprocessing comprises two analog inputs (I , I ), wherein a converter ( ) is connected to each input for generating a first and a second digital value (D , D ) respectively. These are fed to a table ( ) for generating a lookup value (D). A decimation filter ( ) processes several such lookup values and generates an output value (O). With this arrangement the table can be kept comparatively small while it is still possible to reach high resolution and precision. The A/D-converter is especially suited for applications where two or more analog signals have to be combined and digitized.
