On-resistance is matched between switches to 0.5Ω max and is flat (0.5Ω max) over the specified signal range. Each switch can handle Rail-to-Rail ® analog signals. Offleakage current is only 5nA max at TA = +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equipment or applications where current switching is required. They have lower power requirements, use less board space, and are more reliable than mechanical relays. The MAX4661 has four normally closed (NC) switches, and the MAX4662 has four normally open (NO) switches. The MAX4663 has two NC and two NO switches, and features guaranteed break-before-make switching. These devices operate from a single +4.5V to +36V supply or from dual ±4.5V to ±20V supplies. A separate logic supply pin guarantees TTL/CMOS-logic compatibility when operating across the entire supply voltage range.

Connect to GND for singlesupply operation. Ground 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. Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small-signal diodes (D1, D2) in series with the supply pins and a Schottky diode between V+ and VL for overvoltage protection (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 Vshould not exceed 44V. Above 5MHz, circuit board layout becomes critical and it becomes difficult to characterize the response of the switch independent of the circuit. The graphs shown in the Typical Operating Characteristics were taken using a 50Ω source and load connected with BNC connectors to a circuit board deemed “average”; that is, designed with isolation in mind, but not using stripline or other special RF circuit techniques. For critical applications above 5MHz, use the MAX440, MAX441, and MAX442, which are fully characterized up to 160MHz. +15V D1 * * * * MAX4661 MAX4662 MAX4663 NO_ COM_ Off-Isolation at High Frequencies In 50Ω 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. (Above 300MHz, the switch actually passes more signal turned off than turned on.) This effect is more pronounced with higher source and load impedances.
