CS5333 to CS5343/4 Transition
1. INTRODUCTION
The CS5333 and CS5343/4 are complete stereo analog-to-digital converters for digital audio systems. These con-
verters perform sampling, analog-to-digital conversion and anti-alias filtering, generating 24-bit values for both left
and right channels. These small, low-power converters are ideal for systems requiring wide dynamic range and low
noise such as set-top boxes, A/V receivers, DVD-karaoke players, DVD recorders, and automotive applications.
The CS5333 is no longer recommended for new designs, and the CS5343/4 is the suggested replacement.
