The MAX4564 is a low-voltage, dual-supply, single-pole/double-throw (SPDT) analog switch designed to operate from dual ±1.8V to ±6V or single +1.8V to +12V supplies. The low on-resistance (RON = 40Ω at ±5V) and low power consumption (5µW) make this part ideal for audio, video, and battery-powered applications. This switch offers low leakage currents (1nA max) and fast switching speeds (tON = 60ns and tOFF = 40ns at ±5V, max). The MAX4564 is available in 8-pin SOT23 and µMAX packages.
The MAX4564 is a dual‑supply, single‑pole/double‑throw (SPDT) CMOS analog switch designed for audio, video and battery‑powered applications. It operates from dual ±1.8 V to ±6 V or a single +1.8 V to +12 V supply and offers rail‑to‑rail signal handling with virtually no power consumption.
Key features include low on‑resistance (40 Ω typical at ±5 V), ultra‑low leakage (1 nA max), fast switching (tON = 60 ns, tOFF = 40 ns), high off‑isolation (‑77 dB at 1 MHz) and low crosstalk (‑72 dB at 1 MHz). The device is available in 8‑pin SOT‑23 and µMAX packages.
