Description

The MAX4541–MAX4544 are precision, dual analogswitches designed to operate from a single +2.7V to +12Vsupply. Low power consumption (5µW) makes these partsideal for battery-powered equipment. These switches offerlow leakage currents (100pA max) and fast switchingspeeds (tON = 150ns max, tOFF = 100ns max).When powered from a +5V supply, the MAX4541–MAX4544 offer 2Ω max matching between channels, 60Ω max on-resistance (RON), and 6Ω max RON flatness.These switches also offer 5pC max charge injection anda minimum of 2000V ESD protection per Method 3015.7.The MAX4541/MAX4542/MAX4543 are dual single-pole/single-throw (SPST) devices and the MAX4544 is a singlepole/double-throw (SPDT) device. The MAX4541 has twonormally open (NO) switches and the MAX4542 has two normally closed (NC) switches. The MAX4543 has one NO and one NC switch and can be used as an SPDT, while the MAX4544 is an SPDT. The MAX4541/MAX4542/MAX4543 are available in tiny SOT23-8 and 8-pin TDFN packages, and the MAX4544 is available in a SOT23-6 package.Applications+3V, +5V DACs and ADCsAudio and Video SwitchingBattery-Powered ApplicationsCell PhonesCommunication SystemsGuidance and Control SystemsHeads-Up DisplaysMilitary RadiosPagersPBX, PABXSample-and-Hold CircuitsTest EquipmentUltrasound
