Confidential Draft 6/18/07 CS4352 192 kHz Stereo DAC with 2 Vrms Line Out Features  Multi-bit Delta-Sigma Modulator  24-Bit Resolution  Supports Sample Rates up to 192 kHz  106 dB A-wt Dynamic Range  -93 dB THD+N  Integrated Line Driver  2 Vrms Output into 5 kΩ AC Load  Analog Low-Pass Filter  Stereo Mutes with Auto-Mute Function  Low Clock-Jitter Sensitivity  Low-Latency Digital Filtering  Popguard® Technology for Control of Clicks and Pops  Single-Ended Outputs  +3.3 V Core, +9 to 12 V Analog, and +1.5 to 3.3 V Interface Power Supplies  Low Power Consumption  20-pin TSSOP, Lead-Free Assembly Description The CS4352 is a complete stereo digital-to-analog system including digital interpolation, fifth-order multi-bit delta-sigma digital-to-analog conversion, digital de-emphasis, analog filtering, and on-chip 2 Vrms line-level driver. The advantages of this architecture include ideal differential linearity, no distortion mechanisms due to resistor matching errors, no linearity drift over time and temperature, high tolerance to clock jitter, and a minimal set of external components. The CS4352 is available in a 20-pin TSSOP package in both Commercial grade (-40°C to +85°C) and Automotive grade (-40°C to +105°C). The CDB4352 Customer Demonstration Board is also available for device evaluation and implementation suggestions. Please see “Ordering Information” on page 20 for complete details. These features are ideal for cost-sensitive, 2-channel audio systems inc...
