... Reduced Filter Order with the CS35L00 In applications which require an output filter, the unique design of the CS35L00 allows a much smaller, less expensive output filter to be used than what is normally found in Class D amplifiers. In contrast to a second order filter implemented with a series inductive element (traditional inductor or ferrite beads) and a shunt capacitive element, basic filtering for the CS35L00 is accomplished by a single-order capacitive element attached to the OUTx terminals ...

... Many factors affect the switching losses when the device is operated in HD/FHD mode. These factors in- clude the frequency of the content being amplified, the voltage level of VBATT, and the amplitude of the output signal will factor into both the voltage presented across the capacitors and the frequency at which the capacitors are charged or discharged CS35L00 DS906A2 ...

... When pulled to a logic low state, the SD pin tristates the outputs and shuts down the CS35L00 device, put- ting it into a low power mode. 5.4.1 Recommended Power-Up Sequence 1. With the SD pin pulled low, apply power to the CS35L00 and wait for the power supply to be stable. 2. Set the SD pin high to begin normal operation. 5.4.1.1 Zero Crossing on Power-Up Functionality The CS35L00 implements an input-signal zero-crossing detection function that is enabled during power- up. This function is designed to prevent audible artifacts and eliminate any need to mute the amplifier’ ...

... Over Temperature Protection The CS35L00 is internally protected against thermal overload. Built in die temperature sensing circuitry monitors the die temperature and will place the device into shut-down if thermal overload occurs. A ther- mal overload is characterized by the die temperature reaching the Thermal Error Threshold (T time the outputs will tristate and shut down ...

... To ensure high-yield manufacturability, the PCB footprint for the CS35L00 should be constructed with strict adherence to the specifications given in IPC-610. Departure from this specification significantly increases the probability of solder bridging and other manufacturing defects. Routing of the traces into and out of the CS35L00 device should also be given consideration to avoid man- ufacturing issues. 8.3 Package Thermal Performance Class D amplifiers, though highly efficient, produce heat through the process of amplifying the audio signal ...
