MAX4564

Low-Voltage, Dual-Supply,

SPDT Analog Switch with Enable

General Description

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 (R

= 40Ω at

±5V) and low power consumption (5µW) make this part

ideal for audio, video, and battery-powered applica-

tions. This switch offers low leakage currents (1nA

max) and fast switching speeds (t

= 60ns and t

OFF

= 40ns at ±5V, max).

The MAX4564 is available in 8-pin SOT23 and µMAX

packages.
