GENERAL DESCRIPTION The ADG465 is a single channel protector that comes in SOT-23 and MSOP Packages. The channel protector is in series with the signal path and protects sensitive components from voltage transience in the signal path whether or not the power supplies are present. Because the channel protection works regardless of the presence of the supplies, the channel protectors are ideal for use in applications where correct power sequencing cannot always be guaranteed to protect the analog inputs (for example, hot insertion rack systems). See the Applications Information section for further details.
FEATURES Fault and overvoltage protection up to ±40 V Signal paths open circuit with power off Signal path resistance of RON with power on Supply maximum ratings (VDD to VSS): 44 V Low on resistance (RON): 80 Ω typical ±1 nA maximum path current leakage at 25°C Low power dissipation: 0.8 µW typical Latch-up proof construction
