MAXIM MAX4594, MAX4597 User Manual

General Description

The MAX4594–MAX4597 single-pole/single-throw
(SPST) analog switches operate from a single +2.0V to
+5.5V supply. The MAX4594/MAX4596 switches are
normally open (NO), and the MAX4595/MAX4597 are
normally closed (NC). The MAX4596/MAX4597 pinouts
are optimized for the highest SC70 package off-isola­tion available.

These switches have 10Ω max on-resistance (R

ON

),

with 1.5Ω max R

ON

flatness over the analog signal
range when powered from a +5V supply. The
MAX4594–MAX4597 offer low 0.5nA leakage currents
and fast switching times less than 40ns. They are pack­aged in an ultra-small 5-pin SC70 and 6-pin µDFN.

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.

Note 1: Voltages exceeding V+ or GND on any signal terminal are clamped by internal diodes. Limit forward-diode current to maxi-

mum current rating.
