I'm using ADG601 as shown in the image above. When I provide an high value to SHDN i can correctly see VBatt = +VH. On the other hand, when I provide a low value to SHDN i can not see +VH = 0 V.
Can someone help me in understand why?
Thank you very much.
thank you very much for your reply. The answers to your questions are listed here:
1. Vbatt = 3.3V
2. with SHDN low I see +VH = 2.53 V
3. +VH is connected to 6 switches to provide them positive power supply (2 ADG1408 and 4 ADG1404)
4. the low value provided to SHDN is 0V.
