19-2046; Rev 1; 1/07 High-Current, 25, SPDT, CMOS Analog Switches The MAX4659/MAX4660 are medium voltage CMOS analog switches with a low on-resistance of 25 max specifically designed to handle large switch currents. With a switch capability of up to 200mA peak current and 150mA continuous current (MAX4660), and up to 150mA peak current and 75mA continuous current (MAX4659), these parts can switch loads as low as 50. They can replace reed relays with a million times the speed and a 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 their power-supply range. The devices are single-pole/double-throw (SPDT) switches. The MAX4659/MAX4660 contain one normally closed (NC) switch and one normally open (NO) switch. The MAX4659/MAX4660s' 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 off-leakage current is only 1nA max at TA = +25C. The MAX4659 is available in 8-pin MAX(R) and SO packages. The MAX4660 is available in thermally enhanced exposed paddle MAX and SO packages.

No Connection _______________________________________________________________________________________ High-Current, 25, SPDT, CMOS Analog Switches The MAX4659/MAX4660 are single, single-pole/doublethrow (SPDT) CMOS analog 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 MAX4659/MAX4660 have a normally open switch and a normally closed switch. 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 200mA peak current and 150mA 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 operation 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 this 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 voltage drop is approximately 7mV there is an increase in power supply current from 90A to 2mA (typ) 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 maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. First, connect GND, followed by V+, V-, and the remaining pins. If power-supply sequencing is not possible, add two small-signal diodes (D1, D2) in series with supply 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 protection diode for the negative supply is not required when V- is connected to GND. Off-Isolation at High Frequencies In 50 systems, 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, however, it behaves like a capacitor and off-isolation decreases with increasing frequency. This effect is more pronounced with higher source and load impedances. Above 5MHz, circuit board layout becomes critical. The graphs shown in the Typical Operating Characteristics were taken using a 50 source and load connected with BNC connectors.
