Draft CS5343/4 3/10/15 98 dB, 96 kHz, Multi-Bit Audio A/D Converter Features General Description Advanced Multi-Bit Architecture The CS5343/4 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 Audio Sample Rates Up to 108 kHz at sample rates up to 108 kHz per channel. 98 dB Dynamic Range at 5 V The CS5343/4 uses a 3rd-order, multi-bit Delta-Sigma -92 dB THD+N at 5 V modulator followed by a digital filter, which removes the need for an external anti-alias filter. Low-Latency Digital Filter The CS5343/4 also features a high-impedance sam- High-Pass Filter to Remove DC Offsets pling network which eliminates costly external components such as op-amps. Single +3.3 V or +5 V Power Supply The CS5343/4 is available in a 10-pin TSSOP package Power Consumption < 40 mW at 3.3 V for both Commercial (-40 to +85 C) and Automotive Master or Slave Operation grades (-40 to +105 C). The CDB5343 Customer Demonstration Board is also available for device evalu- Slave Mode Speed Auto-Detect ation and implementation suggestions. Please refer to the Ordering Information on page19 for complete Master Mode Default Settings details. 256x or 384x MCLK/LRCK Ratio The CS5343/4 is ideal for audio systems requiring wide CS5343 Supports IS Audio Format dynamic range, negligible distortion and low noise, such as set-top boxes, DVD-karaoke players, DVD record- CS5344 Supports Left-Justified Audio Format ers, A/V receivers, and automotive applications.
