.. CS43L43 Low Voltage, Stereo DAC with Headphone Amp Features ‰16-Pin Description The CS43L43 is a plete stereo digital-to-analog output system including interpolation, 1-bit D/A conversion, analog filtering, volume control, and a headphone amplifier, in a 16-pin TSSOP package. The CS43L43 is based on delta-sigma modulation, where the modulator output controls the reference voltage input to an ultra-linear analog low-pass filter. This architecture allows infinite adjustment of the sample rate between 2 k Hz and 100 k Hz simply by changing the master clock frequency. The CS43L43 contains on-chip digital bass and treble boost, peak signal limiting and de-emphasis. The CS43L43 operates from a +1.8 V to +3.3 V supply and consumes only 16 m W of 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.
