CS5346
2. PIN COMPATIBILITY - CS5345/CS5346 DIFFERENCES
The CS5346 is pin compatible with the CS5345 and is a drop in replacement for CS5345 applications where
VA = 5 V, VD = 3.3 V, VLS
≥
3.3 V, and VLC
≥
3.3 V. The pinout diagram and table below show the requirements
for the remaining pins when replacing the CS5345 in these designs with a CS5346.
