101 dB, 192 kHz Stereo A/D Converter

The CS5340 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 200 kHz per channel.

The CS5340 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 CS5340 is ideal for audio systems requiring wide dynamic range, negligible distortion, and low noise, such as set-top boxes, DVD systems, karaoke systems, effects processors and automotive applications.
