CS5333 to CS5340 Conversion
by Kevin L Tretter
1. Introduction
The CS5333 and CS5340 are complete stereo analog-to-digital converters for digital audio systems.
These converters 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 re-
corders, and automotive applications. The CS5333 is no longer recommended for new designs, and the
CS5340 is the suggested replacement.
This application note identifies the implementation differences between these two devices, including:
-
Key specifications
-
Pinout differences
-
Startup mode selections
-
System clocking
-
Input filter topology
-
Reference pin decoupling
2. Key Specifications
Table 1 shows a comparison of the key specifications of these two devices, and Table 2 shows the pin
comparison between the CS5333 and the CS5340. Although these two devices are not pin compatible,
they are very similar in terms of overall functionality and feature set. The CS5340 achieves higher analog
performance and supports a wider range of output sample rates, including 192 kHz. This additional per-
formance is the main reason for the increased power consumption of the CS5340 relative to the CS5333.
