.. CS43L42 Low Voltage, Stereo DAC with Headphone Amp Features ‰1.8 Description The CS43L42 is a plete 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 k Hz and 100 k Hz 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 m W 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 k Hz sample rate ‰96 d B dynamic range at 3 V supply ‰-85 d B THD+N ‰Low power consumption ‰Digital volume control - 96 d B attenuation, 1 d B step size ‰Digital bass and treble boost - Selectable corner frequencies - Up to 12 d B boost in 1 d B increments ‰Peak signal limiting to prevent clipping ‰De-emphasis for 32 k Hz, 44.1 k Hz, and 48 k Hz ‰Headphone amplifier - up to 25 m Wrms power output into 16 Ω load- - 25 d B analog attenuation and mute - Zero crossing click free level transitions ‰ATAPI mixing functions ‰24-Pin TSSOP package - 1 k Hz sine wave at 3.3V supply CS43L42-KZ CS43L42-KZZ, Lead Free CDB43L42 ORDERING INFORMATION -10 to 70 °C -10 to 70 °C 24-pin TSSOP 24-pin TSSOP Evaluation Board SCL/CCLK/DIF1 SDA/CDIN/DIF0 AD0/CS/DEM0 MUTEC External Mute Control VQ_HP VA_HP RST VA VL Control Port Headphone Amplifier Analog Volume Control Analog Volume Control HP_A Serial...
