Classification: CPC H  G | IPC H

Claim 1:
2. The electronic circuit of claim 1, wherein the second channel includes a second sign comparator, the second digital to analog converter having an output coupled to a first input of the second sign comparator, and the switch network is configured to selectively couple, upon reception of the self-test mode signal signaling a test phase, the output of the first digital to analog converter at a second input of the second sign comparator, the first input of the second sign comparator being maintained coupled to the output of the second digital to analog converter,
the checking circuit being coupled to the output of the first sign comparator and to an output of the second sign comparator, the checking circuit configured to issue the test status signal based on the outputs of the first and second sign comparators.
