CS5351 108 dB, 192 kHz, Multi-bit Audio A/D Converter Features General Description Advanced Multi-bit Delta-Sigma Architecture 24-bit Conversion 108 dB Dynamic Range The CS5351 is a complete analog-to-digital converter for digital audio systems. It performs sampling, analogto-digital conversion, and anti-alias filtering. The device generates 24-bit values for both left and right inputs in serial form at sample rates up to 192 kHz per channel. The CS5351 uses a 5th-order, multi-bit, delta-sigma modulator followed by digital filtering and decimation, which removes the need for an external anti-alias filter. The ADC uses a differential architecture which provides excellent noise rejection. -98 dB THD+N System Sampling Rates up to 192 kHz 135 mW Power Consumption The CS5351 is ideal for audio systems requiring wide dynamic range, negligible distortion, and low noise. Such applications include A/V receivers, DVD-R, CD-R, digital mixing consoles, and effects processors.
