Confidential Draft CS5341 3/11/08 105 dB, 192 kHz, Multi-Bit Audio A/D Converter Features General Description Advanced Multi-bit Delta-Sigma Architecture The CS5341 is a complete analog-to-digital converter for digital audio systems. It performs sampling, analog- 24-bit Conversion to-digital conversion, and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form Supports All Audio Sample Rates Including at sample rates up to 200 kHz per channel. 192 kHz The CS5341 uses a 5th-order, multi-bit Delta-Sigma modulator followed by digital filtering and decimation, 105 dB Dynamic Range at 5 V which removes the need for an external anti-alias filter. The CS5341 is available in a 16-pin TSSOP package -98 dB THD+N for Commercial (-10 to +70 C) and Automotive grades (-40 to +85 C). The CDB5341 Customer Demonstra- 90 mW Power Consumption tion Board is also available for device evaluation and implementation suggestions. Please refer to Ordering High-Pass Filter to Remove DC Offsets Information on page22 for complete ordering information. Analog/Digital Core Supplies from 3.3 V to 5 V The CS5341 is ideal for audio systems requiring wide Supports Logic Levels between 1.8 V and 5 V dynamic range, negligible distortion and low noise, such as set-top boxes, DVD-karaoke players, DVD record- Auto-Detect Mode Selection in Slave Mode ers, A/V receivers, and automotive applications.
