... The digital power limit feature can program the output power limit W/ch, allowing the NCS8353 single system solution in FPTV audio applications. The NCS8353 includes a digital power limit feature. The digital power limiter quickly reduces the internal gain of the amplifier when high amplitude signals would cause excessive clipping on the output ...

... W per channel. This is achieved by the two external power limit pins, PL0 and PL1, which are TTL level compatible change in power limit is desired, the NCS8353 must first be disabled followed by setting a new power limit. Finally, when the NCS8353 is re−enabled, the new power limit will be active ...

... The NCS8353’s short circuit protection is analogous to a power supply’s hiccup mode current limiting operation. When a short is detected the NCS8353 will disable the output stage and will attempt to re-enable the output stage after 180 ms. If the short has been removed then the output stage re-enables and operates normally ...

... When current flows through the voice coil of a loudspeaker it causes the diaphragm to move thus causing a popping and clicking sound. The NCS8353 includes pop and click suppression circuitry that creates a slow ramp to bias the amplifier during the previously mentioned power sequences. In order to eliminate “ ...
