ABSTRACT:
The present invention relates to an integrated input/output interface for low and/or high voltage range signals of the digital and/or analog type. It comprises essentially a power amplification circuit block (2) having at least one low voltage range input terminal (A) and at least one high voltage range output terminal (B), and a second amplification circuit block (3) having a high voltage range input terminal connected to said high voltage range output terminal (B) and at least one low voltage range output terminal (D). A conventional circuit block (4) prevents a high voltage range signal being input to said high voltage range terminal (B) from propagating through the first power amplification circuit block (2), so that it only affects the second amplification circuit block (3). This interface is implemented in mixed high voltage bipolar/CMOS/DMOS technology.
