GENERAL DESCRIPTION

The ADG466 and ADG467 are triple and octal channel protectors, respectively. The channel protector is placed in series with the signal path. The channel protector will protect sensitive components from voltage transience in the signal path whether the power supplies are present or not. Because the channel protection works whether the supplies are present or not, the channel protectors are ideal for use in applications where correct power sequencing can’t always be guaranteed (e.g., hotinsertion rack systems) to protect analog inputs. This is discussed further, and some example circuits are given in the Applications section of this data sheet.
