General Description
Maxim’s MAX4655–MAX4658 are medium-voltage
CMOS analog switches with low on-resistance of 10Ω
max, specifically designed to handle large switch cur-
rents. With a switch capability of up to 400mA peak cur-
rent and 300mA continuous current (MAX4655/
MAX4656), and up to 300mA peak current and 150mA
continuous current (MAX4657/MAX4658), these parts
can switch loads as low as 25Ω. They can replace reed
relays with a million times the speed and virtually unlim-
ited number of lifetime cycles. Normal power consump-
tion is only 3mW, whether the switch is on or off. These
parts are TTL/CMOS compatible and will switch any
voltage within its power-supply range.
These are SPST (single-pole/single-throw) switches.
The MAX4655/MAX4657 are normally closed (NC),
while the MAX4656/MAX4658 are normally open (NO).
The difference between the MAX4655/MAX4656 and
the MAX4657/MAX4658 is in the power dissipation of
their packages. Refer to the Absolute Maximum Ratings
and the Electrical Characteristics.
The MAX4655–MAX4658 power-supply range is from
±4.5V to ±20V for dual-supply operation and +9V to
+40V for single-supply operation. These switches can
operate from any combination of supplies, within a 40V
V+ to V- range. They conduct equally well in either direc-
tion and can handle rail-to-rail analog signals. The off-
leakage current is only 1nA max at TA= +25°C. They are
available in 8-pin µMAX®, TDFN, and SO packages, with
exposed paddle options for high-power applications.

Detailed Description
The MAX4655–MAX4658 are single SPST CMOS ana-
log switches. The CMOS switch construction provides
rail-to-rail signal handling while consuming very little
power. The switch is controlled by a TTL/CMOS level
compatible digital input. The MAX4655/MAX4657 are
normally closed switches, and the MAX4656/MAX4658
are normally open switches.
These devices can be operated with either single
power supplies or dual power supplies. Operation at up
to ±20V supplies allows users a wide switching dynamic
range. Additionally, asymmetrical operation is possible
to tailor performance to a particular application.
These switches have been specifically designed to
handle high switch currents, up to 400mA peak current
and 300mA continuous currents. In order to do this, a
new technique is used to drive the body of the output
N-channel device. (Note: the basic switch between the
input NC/NO terminal, and the output common terminal
consists of an N-channel MOSFET and a P-channel
MOSFET in parallel.) The standard method limits opera-
tion to approximately a 600mV drop across the switch.
More than 600mV causes an increase in IdON leakage
current (due to the turn-on of on-chip parasitic diodes)
and an increase in V+ supply current. With the new
sensing method, there is no limitation to the voltage
drop across the switch. Current and voltage are limited
only by the power dissipation rating of the package and
the absolute maximum ratings of the switch.
When the analog input to output voltage drop is
approximately 7mV there is an increase in power sup-
ply current from typically 90µA to 2mA within a 1mV to
7mV range, caused by the new sensing/driving circuitry.
Applications Information
Overvoltage Protection
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings, because stresses beyond the listed rat-
ings can cause permanent damage to the devices.
First, connect GND, followed by V+, V-, and the remain-
ing pins. If power-supply sequencing is not possible,
add two small signal diodes (D1, D2) in series with sup-
ply pins (Figure 1). Adding diodes reduces the analog
signal range to one diode drop below V+ and one
diode drop above V-, but does not affect the devices’
low switch resistance and low leakage characteristics.
Device operation is unchanged, and the difference
between V+ and V- should not exceed 44V. The protec-
tion diode for the negative supply is not required when
V- is connected to GND.
Off-Isolation at High Frequencies
In 50Ωsystems, the high-frequency on-response of
these parts extends from DC to above 100MHz, with a
typical loss of -2dB. When the switch is turned off, how-
ever, it behaves like a capacitor, and off-isolation
decreases with increasing frequency. This effect is
more pronounced with higher source and load imped-
ances. Above 5MHz, circuit board layout becomes
critical. The graphs shown in the Typical Operating
Characteristics were taken using a 50Ωsource and
load connected with BNC connectors.
