CS43L42

www.DataSheet4U.com CS43L42 Low Voltage, Stereo DAC with Headphone Amp Features ‰1.8 Description 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 +1.8 V to +3.3 V supply and consumes only 16 mW of power with a 1.8 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. to 3.3 Volt supply ‰24-Bit conversion / 96 kHz sample rate ‰96 dB dynamic range at 3 V supply ‰-85 dB THD+N ‰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 25 mWrms power output into 16 Ω load* 25 dB analog attenuation and mute Zero crossing ...
