In datasheet of ADG621, there are few specifications for 3.3v supply operation
but 5v supply. Did we have the specification such as “the switch timing (Ton,
Toff) for +3.3V/0V (VDD/VSS) supply”?
This device is fully characterized and guaranteed with dual and single 5V
supply voltages. For 3.3V supply we only provide typical performance graphs,
but we don’t guarantee any specification.
