The ADG1236 is a dual SPDT switch with features such as low capacitance, low charge injection, ±15 V/12 V iCMOS™, etc.
The ADG1236 is a monolithic iCMOS dual SPDT switch featuring 1.3 pF off‑capacitance, 3.5 pF on‑capacitance, 1 pC charge injection and a 33 V supply range. It operates with no separate logic supply, uses 3 V logic‑compatible inputs, and consumes less than 0.03 µW of power. The device is available in 16‑lead TSSOP and 12‑lead LFCSP packages.
Typical applications include automatic test equipment, data‑acquisition and sample‑and‑hold systems, battery‑powered instruments, audio/video signal routing and communication systems where low glitch and fast settling are required.
