Low-Voltage, Single-Supply,
10Ω SPST CMOS Analog Switches
General Description
____________________________Features
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-isola-
tion available.
♦ Available in 5-Pin SC70 and 6-Pin µDFN Packages
♦ 10Ω max On-Resistance
♦ 1.5Ω max On-Resistance Flatness
♦ Fast Switching

♦ 300MHz -3dB Bandwidth at +25°C
♦ TTL/CMOS-Logic Compatible
♦ -80dB Off-Isolation at 1MHz
♦ 0.5nA max Off-Leakage
These switches have 10Ω max on-resistance (R ),
ON
with 1.5Ω max R
flatness over the analog signal
ON
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 pack-
aged in an ultra-small 5-pin SC70 and 6-pin µDFN.
