The ADG1236 is a low leakage dual SPDT switch that utilizes the iCMOS process, supports ±15V/12V power, 1.3pF of switch OFF capacitance, 3.5pF of switch ON capacitance, 1pC of switch charge injection, 120Ω of switch resistance, and is suitable for automatic test equipment, data acquisition systems, battery-powered systems, sample and hold systems, audio/video signal routing, and communication systems.
The ADG1236 is a monolithic iCMOS dual SPDT switch designed for high‑performance analog applications. It offers ultra‑low off‑capacitance (1.3 pF), low charge injection (1 pC), and operates from a 33 V supply without a separate logic supply.
Typical applications include automatic test equipment, data acquisition, battery‑powered instruments, sample‑and‑hold circuits, and video signal routing. The device is available in 16‑lead TSSOP and 12‑lead LFCSP packages and consumes less than 0.03 µW of power.
