CS4344 Datasheet



The CS4344 is complete, stereo digital-to-analog output systems including interpolation, multi-bit D/A conversion and output analog filtering in a 10-pin package. The CS4344 support all major audio data interface formats, and the individual devices differ only in the supported interface format. The CS4344 is based on a fourth order multi-bit delta-sigma modulator with a linear analog low-pass filter. The CS4344 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 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 is available in a 10-pin TSSOP package in both Commercial (-10 to +85 °C) and Automotive grades (-40 to +85 °C). CS4344 Features • Multi-bit Delta-Sigma Modulator• 24-Bit Conversion• Automatically Detects Sample Rates up to 192 kHz• 105 dB Dynamic Range• -95 dB THD+N• Low Clock Jitter Sensitivity• Single +3.3 V or +5 V Power Supply• Filtered Line Level Outputs• On-Chip Digital De-emphasis• Popguard™ Technology• Small 10-Pin TSSOP Package
