The MAX4695 is a low-voltage, dual single-pole/double-throw (SPDT) analog switch that operates from a single +1.8V to +5.5V supply. The MAX4695 features break-before-make switching action with a tON = 30ns and tOFF = 18ns at +3V. When powered from a +2.7V supply, the device has a 60Ω (max) on-resistance (RON), with 3Ω (max) RON matching and 10Ω (max) RON flatness. The digital logic inputs are 1.8V-logic compatible from a +2.7V to +3.3V supply. The MAX4695 is available in both a space-saving 3mm x 3mm 12-pin TQFN package and a 10-pin µMAX package.
The MAX4695 analog switch from Maxim Integrated operates from a single +1.8 V to +5.5 V supply and provides break‑before‑make switching with 30 ns turn‑on and 18 ns turn‑off times. It is offered in a 12‑pin thin QFN package and a 10‑pin µMAX package, suitable for applications such as MP3 players, battery‑operated equipment, and signal routing.
Key features include low on‑resistance (60 Ω max at +2.7 V), tight matching (3 Ω max), low leakage (100 pA max), high bandwidth (>300 MHz), low crosstalk (‑82 dB at 1 MHz), and low charge injection (4 pC). The device supports 1.8 V CMOS‑logic inputs and can handle rail‑to‑rail analog signals.
