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.
