Low-Voltage, Single-Supply,
SPDT Analog Switch in SC70
General Description
The MAX4599 single-pole/double-throw (SPDT) switch
operates from a +2.0V to +5.5V single supply. It offers
60Ω max on-resistance (R
ON
) at +5V and fast switching
times (t
ON
= 30ns max, t
OFF
= 25ns max).
The MAX4599 features excellent R
ON
flatness (4Ω max)
and matching (1Ω max) between channels. This device
also offers 5pC max charge injection.
The MAX4599 is available in tiny 6-pin SC70, µDFN, and
SOT23 packages.

Note 1:
Signals on NO, NC, COM, or IN exceeding V+ or GND are clamped by internal diodes. Limit forward-diode current to
maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
