The MAX4686/MAX4687/MAX4688 is a single-channel, low-voltage, low-switching-time analog switch that operates from a single +1.8V to +5.5V supply. It features a 6-bump, 0.5mm pitch, UCSP package that saves board space.
The MAX4686, MAX4687 and MAX4688 are low‑on‑resistance, low‑voltage analog switches that operate from a single +1.8 V to +5.5 V supply. The MAX4686 and MAX4687 are single‑pole‑single‑throw (SPST) devices, while the MAX4688 is a single‑pole‑double‑throw (SPDT) switch offering break‑before‑make action. All devices feature a maximum on‑resistance of 2.5 Ω at 3 V, fast switching (tON ≈ 30 ns, tOFF ≈ 12 ns), and rail‑to‑rail logic compatibility.
These switches are supplied in Maxim's chip‑scale UCSP package (1.50 mm × 1.02 mm) and are suited for applications such as MP3 players, cellular phones, power routing, and audio/video signal routing. The data sheet provides absolute maximum ratings, electrical characteristics, dynamic performance, pin descriptions, and recommended layout considerations for the UCSP package.
