Innovative Designs Minimize Board Space Requirements and Lower Total BOM Costs
The new CS4245 stereo CODEC and CS5345
stereo ADC are pin-compatible, highly integrated
audio converters designed for emerging audio
and video applications such as DVD recorders
and home theatre products. The pair strengthens
the Cirrus Logic mixed-signal audio IC portfolio
and provides designers with an integrated
solution that streamlines product development,
reduces overall design complexity and cost, and
delivers premium audio performance.
The front-end of both the CS4245 and CS5345
features an integrated analog input selector to
accommodate up to 6 stereo audio sources.
Also included is a programmable gain amplifier
capable of ±12 dB analog gain in 0.5 dB step
sizes with zero crossing, click-free transitions to
maintain sonic quality. One pair of inputs has a
dedicated microphone pre-amplifier in its path
that provides +32 dB of gain, and there is also a
low-noise microphone bias supply available.
A multi-bit Delta-Sigma stereo A/D converter
provides 24-bit conversion and output sample
rates up to 192 kHz. A high-pass filter is included
for DC offset removal, and a dedicated pin is
available for detecting overflow conditions.

The 24-bit, 192 kHz stereo DAC in the CS4245
is also based on a multi-bit Delta-Sigma archi-
tecture, includes digital attenuation, and pro-
vides high quality single-ended outputs with
Cirrus Logic’s patented Popguard technology to
eliminate power cycling clicks and pops, further
reducing the number of external components
required. The sample rates for the ADC and
DAC in the CS4245 can be independent of each
other for flexibility is system configuration.
The CS4245 and CS5345 operate from either
a +3.3 V or +5 V power supply and have +1.8 V
to +5 V logic power supplies for the control and
serial port to allow for direct interface to external
processors or micro-controllers without level
shifting.
Engineered for performance, this new CODEC
and ADC pair delivers professional audio quality
at a breakthrough price point.
