Q
Can switches and multiplexers be operated with logic power supplies less than
those specified in the data sheet, eg. with 3.3 volts.
A
Specifically the ADG412 is specified from 4.5 to 5.5V i.e. 5V +/-5%. If you go
outside this range then the device is not guaranteed to function reliably or to
specification.
Our ADG1212 is compatible with TTL levels (Vih = 2V minimum) and has no digital
supply pin - it is simply powered from the analog supply (+12V or +/-15V).
