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
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.

3. CHARACTERISTICS AND SPECIFICATIONS
RECOMMENDED OPERATING CONDITIONS
AGND = DGND = 0 V; All voltages with respect to ground.
ABSOLUTE MAXIMUM RATINGS
AGND = DGND = 0 V All voltages with respect to ground. (Note 1)
Notes: 1. Operation beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.
2. Any pin except supplies. Transient currents of up to ±100 mA on the analog input pins will not cause
SCR latch-up.
