Pin Compatibility - Cs5345/Cs5346 Differences - Cirrus Logic CS5346 Manual

2. PIN COMPATIBILITY - CS5345/CS5346 DIFFERENCES

The CS5346 is p in compatible with the CS5345 and is a drop in replacement for CS5345 applications where
VA = 5 V, VD = 3.3 V, VLS
for the remaining pins when replacing the CS5345 in these designs with a CS5346.
