MAX4564
General Description
The MAX4564 is a low-voltage, dual-supply, singlepole/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.
