GENERAL DESCRIPTION
The ADG5462F contains four channels that are over
voltage protected. The channel protector is placed in series with the signal path and protects sensitive components from over
voltage faults in that path. The channel protector prevents over
voltages when powered and unpowered, and it is ideal for use in applications where correct power supply sequencing cannot always be guaranteed. The primary supply
voltages define the on-resistance profile, while the secondary supply
voltages define the
voltage level at which the over
voltage protection engages.
When no power supplies are present, the channel remains in the off condition, ...
