An electrostatic discharge protection device comprises several thyristors which are connected in parallel between two nodes of an electrical circuit. It also includes a control circuit having an output connected to the control trigger terminal input of each of the thyristors. In response to an abnormal variation in a voltage between the two nodes being detected, the control circuit initiates a triggering current on the output so as to trigger the thyristors to conduct current between the two nodes. Preferably, the thyristors are arranged in a semiconductor substrate so as to have low hold voltages and small geometrical dimensions.

A device for self-testing of an analog-to-digital converter includes elements for applying to the converter test signals and analyzing elements. The analyzing elements include common resources ( ) integrated in the circuit bearing the converter and capable of being configured to determine successively shift, gain and non-linearities of the converter and elements for configuring and controlling the common resources ( ) so as to adapt them to the characteristics to be determined.
