The ADG436 is a monolithic CMOS device comprising two independently selectable SPDT switches. It is designed on an LC2MOS process, which provides low power dissipation yet gives high switching speed and low on resistance. The on resistance profile is very flat over the full analog input range, ensuring good signal integrity. It is suitable for audio and video switching, battery-powered systems, test equipment and communications systems.
The ADG436 is a monolithic CMOS dual SPDT switch designed for low power dissipation, high switching speed and low on‑resistance. It operates from either dual or single supplies and offers a wide analog signal range, making it suitable for audio, video, communications and battery‑powered systems.
Key features include a typical on‑resistance of 12 Ω, low leakage currents (down to 0.005 nA), fast turn‑on/off times (70 ns/145 ns typical), and break‑before‑make switching. The device supports supply voltages up to ±15 V (dual) or 0‑12 V (single) and includes ESD protection.
| Supply voltage (dual) | Vop = +15 V, Vss = –15 V |
|---|---|
| On‑resistance (Ron) | 12 Ω typ |
| Off‑state leakage current | 0.005 nA typ |
| Input high voltage (digital) | 24 V min |
| Turn‑on delay (ton) | 70 ns typ |
| Maximum supply voltage difference | 44 V |
The device can tolerate up to a 44 V difference between Vop and Vss.
The typical on‑resistance is 12 Ω.
The off‑state leakage current is typically 0.005 nA.
First apply Vpp, then Vss, and finally the logic signals before presenting external signals to the switch.
