ADG465 is a single channel protector in an SOT-23 package, that can protect sensitive components from voltage transients
The ADG465 single‑channel protector is designed for hot‑insertion rack systems and other applications where power‑sequencing cannot be guaranteed. It protects sensitive analog inputs by clamping over‑voltage conditions while presenting a low series resistance of 80 Ω when power is present.
The device combines n‑channel and p‑channel MOSFETs with trench isolation to provide latch‑up‑proof operation and sub‑microampere fault currents. It is available in 6‑lead SOT‑23 and 8‑lead SOIC packages.
| Fault and Overvoltage Protection | ±40 V |
|---|---|
| On‑Resistance (RON) | 80 Ω typ |
| Path Current Leakage (powered) | 1 nA max @ +25 °C |
| Power Dissipation | 0.8 µW typ |
| Maximum Supply Voltage | 44 V |
It can withstand continuous voltage inputs from –40 V to +40 V.
The on‑resistance is 80 Ω typical.
Yes, it uses trench isolation for latchup‑proof construction.
