CS4344/5/8 10-Pin, 24-Bit, 192 kHz Stereo D/A Converter Features Description The CS4344 family members (CS4344, CS4345, and Multi-bit Delta-Sigma Modulator CS4348) are complete, stereo digital-to-analog output systems including interpolation, multibit D/A conversion 24-bit Conversion and output analog filtering in a 10-pin package. The CS4344 family supports major audio data interface for- Automatically Detects Sample Rates up to mats. Individual devices differ only in the supported 192 kHz. interface format. 105 dB Dynamic Range The CS4344 family is based on a fourth-order multibit delta-sigma modulator with a linear analog low-pass fil- -90 dB THD+N ter. This family also includes autospeed mode detection using both sample rate and master clock ratio as a Low Clock-Jitter Sensitivity method of auto-selecting sampling rates between 2 kHz and 200 kHz. Single +3.3 or +5 V Power Supply The CS4344 family contains on-chip digital deempha- sis, operates from a single +3.3 V or +5 V power supply, Filtered Line-Level Outputs and requires minimal support circuitry. These features are ideal for DVD players & recorders, digital televi- On-chip Digital De-emphasis sions, home theater and set top box products, and automotive audio systems. Popguard Technology The CS4344 family is available in a 10-pin TSSOP Small 10-pin TSSOP Package package in both Commercial (-10 to +85 C) and Auto- motive grades (-40 to +85 C). See Section 8.
