CS5361
114 dB, 192 kHz, Multi-Bit Audio A/D Converter
Features
General Description
The CS5361 is a complete analog-to-digital converter for
digital audio systems. It performs sampling, analog-to-
digital conversion and anti-alias filtering, generating 24-
bit values for both left and right inputs in serial form at
sample rates up to 192 kHz per channel.
z Advanced Multi-bit Delta-Sigma Architecture
z 24-Bit Conversion
z 114 dB Dynamic Range
z -105 dB THD+N
z System Sampling Rates up to 192 kHz
z Less than 150 mW Power Consumption
z High Pass Filter or DC Offset Calibration
z Supports Logic Levels Between 5 and 2.5V
z Differential Analog Architecture
z Linear Phase Digital Anti-Alias Filtering
z Overflow Detection
The CS5361 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.
The CS5361 is ideal for audio systems requiring wide dy-
namic range, negligible distortion and low noise, such as
A/V receivers, DVD-R, CD-R, digital mixing consoles,
and effects processors.
