The ADG1433 and ADG1434 are monolithic industrial CMOS (iCMOS®) analog switches comprising three independently selectable single-pole, double-throw (SPDT) switches and four independently selectable SPDT switches, respectively. All channels exhibit 4.7 Ω maximum on resistance, 0.5 Ω on resistance flatness, 3 V logic-compatible inputs, up to 115 mA of continuous current per channel, rail-to-rail operation, break-before-make switching action, and 16-/20-lead TSSOP and 4 mm × 4 mm LFCSP_VQ packages.
The ADG1433 and ADG1434 are monolithic iCMOS analog switches that provide three (ADG1433) or four (ADG1434) independently selectable SPDT switches. They feature break‑before‑make switching, rail‑to‑rail operation, and low power dissipation, making them suitable for portable, battery‑powered instruments and data‑acquisition systems.
Typical applications include relay replacement, audio/video routing, automatic test equipment, data acquisition, avionics, medical equipment and other battery‑powered or high‑performance analog systems. The datasheet lists detailed specifications, pin configurations, absolute maximum ratings and functional block diagrams for both +15 V dual‑supply and single‑supply versions.
| On‑Resistance flatness | 0.5 Ω |
|---|---|
| Continuous current per channel | 115 mA (ADG1433) / 100 mA (ADG1434) |
| Dual‑supply voltage range | +15 V / –15 V |
| Input high voltage (Vin) | 2.0 V min |
| Typical transition time | 140 ns |
| Break‑before‑make delay (typ) | 40 ns |
| Power requirements (dual supply) | Vop = +16.5 V, Vss = –16.5 V |
| Absolute maximum Vop‑Vss rating | 35 V |
Each channel can handle up to 115 mA for ADG1433 and up to 100 mA for ADG1434.
They operate with a +15 V dual supply (Vop = +15 V, Vss = –15 V) and also with a +12 V single‑supply version.
The typical transition time is 140 ns.
