What parts of the Microchip datasheet do you not understand? (Pls give paragraph numbers & figure numbers.) Your question #1 is unclear to me; are you asking whether you can shut down only one half of a dual pot device?Need detail explanation about:
1. SHDN pin12 and sketch config, how to ignore SHDN cause of only one piece?
2. same as above of the CS pin1?
3. how to wiring wp pin11?
Thanks
