Abstract
The present invention relates to a circuit configuration with an A/D converter, especially for applications that are critical in terms of safety, which is especially characterized by a ramp signal generator for generating a ramp voltage that is delivered to the input of the A/D converter, and a test circuit for activating a test cycle which comprises a first run of the ramp, by which a reference measurement of the ramp signal generator is carried out for compensating component tolerances, and comprises a second run of the ramp where an error signal is output when the value that is calculated for a transmission characteristic of the A/D converter lies outside a predetermined tolerance range of the measured value of the transmission characteristic.
