CS5351
108 dB, 192 kHz, Multi-bit Audio A/D Converter
Features General Description
Advanced Multi-bit Delta-Sigma Architecture The CS5351 is a complete analog-to-digital converter
for digital audio systems. It performs sampling, analog-
to-digital conversion, and anti-alias filtering. The device
24-bit Conversion
generates 24-bit values for both left and right inputs in
serial form at sample rates up to 192 kHz per channel.
108 dB Dynamic Range
The CS5351 uses a 5th-order, multi-bit, delta-sigma
-98 dB THD+N
modulator followed by digital filtering and decimation,
which removes the need for an external anti-alias filter.
System Sampling Rates up to 192 kHz
The ADC uses a differential architecture which provides
excellent noise rejection.
135 mW Power Consumption
The CS5351 is ideal for audio systems requiring wide
dynamic range, negligible distortion, and low noise.
High-Pass Filter and DC Offset Calibration
Such applications include A/V receivers, DVD-R, CD-R,
digital mixing consoles, and effects processors.
Supports Logic Levels Between 5 and 2.5 V
