... The CS43L43 contains on-chip digital bass and treble boost, peak signal limiting and de-emphasis. The CS43L43 operates from a +1 +3.3 V supply and consumes only power with a 1.8 V supply. These features are ideal for portable CD, MP3 and MD players and other portable playback systems that require extremely low power consumption ...

... Popguard Transient Control ® The CS43L43 uses Popguard and power-down. This technology, when used with external DC-blocking capacitors in series with the au- dio outputs, minimizes the audio transients commonly produced by single-ended single-supply converters activated inside the DAC when the RST pin is enabled/disabled and requires no other external control, aside from choosing the appropriate DC-blocking capacitors ...

... GND. The time that the device must remain in the power-down state is related to the value of the DC-blocking capacitance and the output load. For example, with a 220 µF capacitor and a 16 Ω load, the minimum power-down time will be approximately 0.4 seconds. 10 CS43L43 and audio output be- Q DS479PP3 ...

... Enabled Function: The CS43L43 will limit the maximum signal amplitude to prevent clipping when this function is enabled. Peak Signal Limiting is performed by first decreasing the Bass and Treble Boost Levels. If the signal is still clipping, then the digital attenuation is increased. The attack rate is determined by the Limiter Attack Rate register ...
