MAX4658ESA+

P1-P3P4-P6P7-P9P10-P12
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 T
A
= +25°C. They are
available in 8-pin µMAX
®
, TDFN, and SO packages, with
exposed paddle options for high-power applications.

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.
