114 dB, 192 kHz 4-, 6- and 8-Channel A/D Converters
The CS5368 is a premium-performance audio A/D converter (ADC) designed for today’s demanding surround-sound consumer and multichannel pro audio applications. The highly integrated IC provides designers with a space-saving solution that streamlines product development, reduces design complexity and lowers overall system costs compared to boards that use multiple stereo ADCs for surround-sound or multichannel designs. Resulting in smaller audio equipment that can be produced at a lower cost compared to today’s products. The CS5368 is the industry’s first audio ADC to support a high-speed TDM interface which provides a serial output of 8 channels of audio data with sample rates up to 192 kHz within a single data stream. This capability reduces layout complexity and relieves input/output constraints in digital signal processors. The on-chip level-shifter and oscillator drivers further reduce complexity and simplify system design. The IC also features a differential architecture that provides excellent noise rejection and performs sampling, A/D conversion and anti-alias filtering. The CS5368 uses a 5th-order, multibit Delta Sigma architecture that provides superior 114 dB dynamic range and negligible distortion. Low-latency digital filtering, with the industry’s shortest group delay, further preserves the original audio quality and experience, making the ICs ideal for real-time and live-sound applications. The flagship CS5368 is an 8-channel converter and the CS5364 and CS5366 are its pin compatible 4- and 6-channel family members.
