The MAX4737/MAX4738/MAX4739 low-voltage, low on-resistance (RON), quad single-pole/single throw (SPST) analog switches operate from a single +1.8V to +5.5V supply. These devices are designed for USB 1.1 and audio switching applications.The MAX4737/MAX4738/MAX4739 feature 4.5Ω RON(max) with 1.2Ω flatness and 0.4Ω matching between channels. These new switches feature guaranteed operation from +1.8V to +5.5V and are fully specified at 3V and 5V. These switches offer break-before-make switching (1ns) with tON<80ns and tOFF<40ns at +2.7V. The digital logic inputs are +1.8V logic compatible with a +2.7V to +3.6V supply.These switches are packaged in a chip-scale package (UCSP™), significantly reducing the required PC board area. The chip occupies only a 2mm x 2mm area and has a 4 x 4 bump array with a bump pitch of 0.5mm. These switches are also available in a 14-pin TSSOP package.ApplicationsAudio/Video Signal RoutingBattery-Operated EquipmentCommunications CircuitsData Acquisition SystemsLow-Voltage Data-Acquisition SystemsSample-and-Hold Circuits

The MAX4729/MAX4730 single-pole/double-throw (SPDT) switches operate from a single supply ranging from +1.8V to +5.5V. These switches provide low 3.5Ω on-resistance (RON), as well as 0.45Ω RONflatness with a +2.7V supply. These devices typically consume only 1nA of supply current, making them ideal for use in lowpower, portable applications. The MAX4729/MAX4730 feature low-leakage currents over the extended temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics.The MAX4729/MAX4730 are available in small 6-pin SC70 and 6-pin µDFN packages. The MAX4729/MAX4730 are offered in three pinout configurations to ease design. The MAX4729/MAX4730 are specified over the extended -40°C to +85°C temperature range.ApplicationsAudio/Video Signal RoutingBattery-Operated EquipmentCommunications CircuitsLow-Voltage Data-Acquisition SystemsRelay ReplacementSample-and-Hold Circuits

The MAX4736 is a low on-resistance, low-voltage, dual single-pole/double throw (SPDT) analog switch that operates from a single 1.6V to 4.2V supply. This device has fast switching speeds (tON= 25ns, tOFF= 20ns max), handles rail-to-rail analog signals, and consumes less than 4µW of quiescent power. The MAX4736 has break-before-make switching.When powered from a 3V supply, the MAX4736 features low 0.6Ω on-resistance (RON), with 0.1Ω RONmatching and 0.05Ω RONflatness. The digital logic input is 1.8V CMOS compatible when using a single 3V supply.The MAX4736 has one normally open (NO) switch and one normally closed (NC) switch, and is available in 12-pin TQFN-EP (3mm x 3mm), QFN-EP (3mm x 3mm), 10-pin µMAX and 10 pin µDFN (2mm x 2mm) packages.ApplicationsAudio/Video Signal RoutingBattery-Powered ApplicationsCell PhonesCommunication SystemsHard DrivesLow-Voltage Data-Acquisition SystemsModemsPCMCIA CardsPower Routing

The MAX4740/MAX4740H low on-resistance (0.61Ω typ) analog switches operate from a single 1.6V to 5.5V supply. The MAX4740/MAX4740H are quad, single-pole, double-throw (SPDT) switches and are configured to route audio signals. The MAX4740/MAX4740H are pin-to-pin compatible parts with the ST Microelectronics quad SPDT STG3699 analog switch.The MAX4740 is a quad SPDT switch and the MAX4740H is a quad SPDT switch that can be placed in a high-impedance mode. Switching logic is controlled by 2 control bits (CB1 and CB2). The MAX4740/MAX4740H also feature a low on-resistance match (0.06Ω) and low power-supply current (0.3µA), which increases battery life.The MAX4740/MAX4740H are available in a tiny 3mm x 3mm, 16-pin TQFN-EP, and 2.5mm x 2.5mm, 16-pin ultra-thin QFN packages.ApplicationsCellular PhonesNotebook ComputersPDAs and Other Handheld Devices
