ADG465BRTZ-REEL7

ADG465 is a single channel protector. 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 analogue inputs (for example, hot insertion rack systems). A channel protector consists of an N channel, metal-oxide semiconductor field-effect transistor (MOSFET), a P channel MOSFET, and another N channel MOSFET connected in series. The channel protector behaves like a series resistor during normal operation, that is, (VSS + 1.5V) <lt/> VIN <lt/> (VDD -1.5V). It is used in application such as ATE equipment, sensitive measurement equipment, hot insertion rack systems, ADC input channel protection etc.
