The ADG1219 is a low-capacitance, low-charge-injection iCMOS SPDT switch that operates at ±15 V/12 V and is packaged in an SOT-23 package.
The ADG1219 is a monolithic iCMOS® SPDT switch featuring ultra‑low charge injection (<0.5 pC) and low off‑capacitance (2.5 pF). It operates with dual supplies of ±15 V or a single 12 V supply and is compatible with 3 V logic inputs, making it suitable for automatic test equipment, data‑acquisition systems, battery‑powered instruments, sample‑and‑hold circuits, audio/video routing and communication applications.
The device is supplied in an 8‑lead SOT‑23 package, offers a typical on‑resistance of 120 Ω, and provides high isolation (77 dB) and low leakage currents (≈±0.004 nA). Detailed specifications, pin configurations, performance curves, and ordering information are included in this datasheet.
