Cirrus Logic reserves the right to modify this product without notice. Features 16-Pin TSSOP Package 1.8 to 3.3 Volt Supply 24-Bit Conversion / 96 kHz Sample Rate 94 dB Dynamic Range at 3 V Supply -85 dB THD+N at 1.8 V Supply Low Power Consumption Digital Volume Control • 96 dB Attenuation, 1 dB Step Size Digital Bass and Treble Boost • Selectable Corner Frequencies • Up to 12 dB Boost in 1 dB Increments Peak Signal Limiting to Prevent Clipping De-emphasis for 32 kHz, 44.1 kHz, and 48 kHz Headphone Amplifier • up to 22 mWrms Power Output into 16 Ω Load* • 25 dB Analog Attenuation and Mute • Zero Crossing Click-free Level Transitions ATAPI Mixing Functions Description The CS43L43 is a complete stereo digital-to-analog out- put system including interpolation, 1-bit D/A conversion, analog filtering, volume control, and a headphone ampli- fier, in a 16-pin TSSOP package. The CS43L43 is based on delta-sigma modulation, where the modulator output controls the reference volt- age input to an ultra-linear analog low-pass filter. This architecture allows infinite adjustment of the sample rate between 2 kHz and 100 kHz 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 mW 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.
