I use the ADG3304 - Pin VCCY, VCCY, GND, and Enable (ON) defined.
The parts heats up mementarily I power up the part. Could you please give me
the reason - how to prevent this?


You need to have a defined level for A or the Y - Inputs

otherwise the two internal amplifiers would work against each other.

customer measurements - after proposal:

a) please set Enable to GND - does the part heat up? NO Heat . 

b) please set a1, A2, A3 A4 to 0V - does the part heat up?  NO Heat  

c) please set A1, A2, A3, A4 to VccA - does the part heat up?  NO Heat .
