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 ADG467 is an octal channel protector designed to protect sensitive analog inputs from voltage transients, even when power supplies are absent. It offers fault and over‑voltage protection up to ±40 V, low on‑resistance (62 Ω typical) and microampere‑level fault current, making it suitable for ATE equipment, sensitive measurement devices, and hot‑insertion rack systems.
The device is supplied in 18‑lead SOIC and 20‑lead SSOP packages, operates from ±15 V supplies, and features trench isolation for latch‑up proof construction. Detailed specifications, pin configurations, performance curves, and application circuits are provided in the document.
| Fault and over‑voltage protection range | ±40 V |
|---|---|
| Typical on‑resistance (RON) | 62 Ω |
| Typical power dissipation | 0.8 µW |
| Absolute maximum VDD to VSS | +44 V |
| Operating temperature range (Industrial) | -40 °C to +85 °C |
| Fault‑free analog signal range (low side) | VSS + 1.5 V (typ) |
| Output open‑circuit voltage (high side) | VDD − 1.5 V (typ) |
It can withstand continuous voltage inputs from –40 V to +40 V.
The typical on‑resistance is 62 Ω.
