... NXP Semiconductors 7.2 Output stage The output stage of each amplifier channel consists of two PMOS power transistors and two NMOS transistors in a BTL configuration. The process used is the BCDMOS process with an isolated substrate, Silicon On Insulator (SOI) process, which has almost no parasitic components and therefore prevents latch-up. ...

NXP Semiconductors 7.7 Standby and mute operation The function of the STB pin is different in legacy mode and I 7.7.1 Legacy mode (pin ADSEL connected to ground) The function of the STB pin will change from standby/operating to standby/mute/operating and the amplifier will start directly when the STB is put into mute or operating mode. Mute operating is controlled via an internal timer (20 ms) to minimize mute-on pops ...

... NXP Semiconductors When the SVR capacitor has discharged, the amplifier starts up again if the V above the low V outputs of the amplifier remain low typically 5 V, results in setting bit DB2[D7] and not starting of the amplifiers but waiting for C-bus command to start. The amplifier prevents audio pops during engine start. To prevent pops on the output caused by the application during an engine start (for instance tuner regulator out of regulation), the STB pin can be made zero when an engine start is detected ...
