Description

Maxim"s MAX4655– are medium-voltage CMOS analog switches with low on-resistance of 10Ω max, specifically designed to handle large switch currents. With a switch capability of up to 400mA peak current 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 unlimited number of lifetime cycles. Normal power consumption 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_ in the full data sheet.

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 direction and can handle rail-to-rail analog signals. The offleakage 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.
