The CS4344 family of products are complete, stereo audio digital/analog converter (DAC) output systems that include interpolation, multibit D/A conversion and output analog filtering in a 10-pin package. These DACs 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 multibit 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 kHz and 200 kHz.
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 and recorders, digital televisions, home theater, set-top box products and automotive audio systems.
The CS4344 family is available in a 10-pin TSSOP package in both commercial (-10 to +85 degrees C) and automotive grades (-40 to +85 degrees C).
