CS5361 Overview
The CS5361 is a complete audio A/D converter (ADC) for digital audio systems. It performs sampling, A/D 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. The CS5361 uses a fifth-order, multibit 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 dynamic range, negligible distortion and low noise, such as audio/video receivers, DVD-R, digital mixing consoles, effects processors and automotive systems.
