High-Current, 10Ω, SPST, CMOS
Analog Switches
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 pad options for high-power applications.
