Analog Devices ADG467 Manuals

The ADG467 is an octal channel protector that protects sensitive components from voltage transience in the signal path. It features fault and overvoltage protection, low on resistance, low power dissipation, and latch-up proof construction.

The ADG466 and ADG467 from Analog Devices are triple and octal channel protectors, respectively, that protect sensitive components from voltage transients in the signal path regardless of the presence or absence of the power supplies. Since the channel protection works regardless of whether the supplies are present, the channel protectors are ideal for use in applications where correct power sequencing cannot always be guaranteed (e.g., hot-insertion rack systems) to protect analog inputs. This is discussed further, and some example circuits are given in the Applications section of this data sheet.
