CS43L42 Low Voltage, Stereo DAC with Headphone Amp to Volt supply conversion / 96 kHz sample rate dB dynamic range at 3 V supply dB THD+N power consumption volume control • 96 dB attenuation, 1 dB step size bass and treble boost • Selectable corner frequencies • Up to 12 dB boost in 1 dB increments signal limiting to prevent clipping for 32 kHz, kHz, and 48 kHz amplifier • up to 25 mWrms power output into 16 load* • 25 dB analog attenuation and mute • Zero crossing click free level transitions mixing functions TSSOP package * 1 kHz sine wave at 3.3V supply The CS43L42 is a complete stereo digital-to-analog output system including interpolation, 1-bit D/A conversion, analog filtering, volume control, line level outputs, and a headphone amplifier, in a 24-pin TSSOP package. The CS43L42 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 kHz and 100 kHz simply by changing the master clock frequency. The CS43L42 contains on-chip digital bass and treble boost, peak signal limiting, and de-emphasis. The CS43L42 operates from a V to V supply and consumes only 16 mW of power with a V supply with the line amplifier powered-down. These features are ideal for portable CD, MP3 and MD players and other portable playback systems that require extremely low power consumption.
