Abstract
The invention relates to a digital processing circuit comprising an analog/digital converter (1) situated at the input of the circuit, a device (2) for the digital processing of the signal emanating from the analog/digital converter and a digital/analog converter (3) situated at the output of the processing circuit. The digital processing circuit comprises means (A2, A3, T, RS, R1) making it possible to control its gain from a single voltage reference (VB). Preferably, the single voltage reference is a bandgap voltage and the circuit is made in CMOS technology. The invention applies to any type of audio or video equipment using such circuits.
