Abstract: A die of an integrated circuit (IC) for implementing an audio amplifier comprises means (500) configured to generate at least one pulse-width-modulated signal (DS) in response to at least one first clock signal ( CLK2 ), and a first set of pads (502), wherein each pad of the first set of pads (502) is configured to provide a respective amplified pulse-width-modulated signal (ADS) to a respective external low-pass or band-pass filter (208). An amplifier stage (20) receives at input the at least one pulse-width-modulated signal (DS) and provide at output the amplified pulse-width-modulated signals (ADS). The die comprises further two power supply pads (300, 302), two pads (400, 402) configured to be connected to an external inductor (L), and a second set of pads (306, 308, 3100), wherein each pad of the second set of pads (306, 308, 310) is configured to provide a respective regulated voltage ( Vfloat, V1, V2 ). An electronic converter circuit (30) is configured to generate the regulated voltages ( Vfloat, V1, V2 ) in order to supply the amplifier stage (20).

Abstract: An analysis unit (390) formed by an analysis body (394) housing an analysis chamber (392) and having a sample inlet (391B) and a supply channel (393) configured to fluidically connect the sample inlet to the analysis chamber (392). Dried assay reagents (395) are arranged in the analysis chamber and are contained in an alveolar mass. For instance, the alveolar mass is a lyophilised mass formed by excipients and by assay-specific reagents.

Abstract: Application data and error correction code (ECC) checkbits associated with that application data are stored in a first memory (24). The ECC checkbits, but not the application data, are stored in a second memory (26). In response to a request to read the application from the first memory (24), the ECC checkbits from the first memory are also read and used to detect, and possibly correct, errors in the read application data. The ECC checkbits are further output from both the first and second memories for bit-by-bit comparison (60). In response to a failure of the bit-by-bit comparison, a signal (SRAM_OK) indicating possible malfunction of one or the other or both of the first and second memories (24, 26) is generated.
