CS4348 Datasheet | Cirrus Logic

Features ! Multi-bit Delta-Sigma Modulator ! 24-bit Conversion ! Automatically Detects Sample Rates up to Description The CS4344 family members are plete, stereo digital-to-analog output systems including interpolation, multi-bit D/A conversion and output analog filtering in a 10-pin package. The CS4344/5/6/8 support all major audio data interface formats, and the individual devices differ only in the supported interface format. The CS4344 family is based on a fourth order multi-bit delta-sigma modulator with a linear analog low-pass filter. This family also includes auto-speed mode detection using both sample rate and master clock ratio as a method of auto-selecting sampling rates between 2 k Hz and 200 k Hz. The CS4344 family contains on-chip digital de-emphasis, operates from a single +3.3 V or +5 V power supply, and requires minimal support circuitry. These features are ideal for DVD players & recorders, digital televisions, home theater and set top box products, and automotive audio systems. The CS4344 family is available in a 10-pin TSSOP package in both mercial (-10 to +85 °C) and Automotive grades (-40 to +85 °C). Please see Section 8. “Ordering Information” on page 23 for plete details. 192 k Hz. ! 105 d B Dynamic Range ! -90 d B THD+N ! Low Clock-Jitter Sensitivity ! Single +3.3 V or +5 V Power Supply !
