MAXIM MAX4635, MAX4636 Technical data

General Description

The MAX4635/MAX4636 are fast, dual 4Ω singlepole/double-throw (SPDT) analog switches that operate with supply voltages from +1.8V to +5.5V. High switching speeds, 1Ω on-resistance flatness, and low power consumption make these devices ideal for audio/video, communications, and battery-operated devices. Containing two independently controllable SPDT switches in 10-pin µMAX and 10-pin 3mm x 3mm thin QFN packages, the MAX4635/MAX4636 use little board space, and have low power consumption ensuring minimal impact on your power budget. The analog signal range extends to the supply rails. The MAX4635 has inverted logic compared to the MAX4636.

Detailed Description

The MAX4635/MAX4636 are low-on-resistance (RON), low-voltage, dual SPDT analog switches that operate from a +1.8V to +5.5V supply. The MAX4635/MAX4636 feature very fast switching speed (tON= 14ns max, t

OFF

= 6ns max) and guaranteed break-before-make switching. The low maximum RONallows high continuous currents to be switched in a variety of applications.

Applications Information

Logic Inputs

The MAX4635/MAX4636 logic inputs (IN1, IN2) can be driven up to +5.5V, regardless of the voltage on V+. This allows interfacing to 5V logic signals while operating with a +3.3V supply voltage without external level translation.

Analog Signal Levels

Analog signals ranging over the entire supply voltage (V+ to GND) can be passed with very little change in on-resistance (see Typical Operating Characteristics). The switches are bidirectional, so the NO_, NC_, and COM_ pins may be used as either inputs or outputs.

Power-Supply Sequencing and

Overvoltage Protection

Caution: Do not exceed the absolute maximum ratings because stresses beyond the listed ratings can cause permanent damage to the device. Proper

power-supply sequencing is recommended for all CMOS devices. Always apply V+ before applying analog signals, especially if the analog signal is not current limited. If this sequencing is not possible, and if the analog inputs are not current limited to less than 30mA, add a small-signal diode (D1) as shown in Figure 5. If the analog signal can dip below GND, add D2. Adding protection diodes reduces the analog range to a diode drop (about 0.7V) below V+ (for D1), and a diode drop above ground (for D2).

On-resistance increases slightly at low supply voltages. Maximum supply voltage (V+) must not exceed +6V. Adding protection diode D2 causes the logic threshold to be shifted relative to GND. Protection diodes D1 and D2 also protect against some overvoltage situations. With Figure 5’s circuit, if the supply voltage is below the absolute maximum rating, and if a fault voltage up to the absolute maximum rating is applied to an analog signal pin, no damage results.
