The MAX4426/MAX4427/MAX4428 are dual monolithic MOSFET drivers designed to translate TTL/CMOS inputs to high voltage/current outputs. The MAX4426 is a dual inverting power MOSFET driver. The MAX4427 is a dual noninverting power MOSFET driver, and the MAX4428 contains one inverting section and one noninverting section. Delay times are nearly independent of VDD(seeTypical Operating Characteristicsin the full data sheet). High-current output drivers rapidly charge and discharge the gate capacitance of even the largest power MOSFETs to within millivolts of the supply rails. This produces the power MOSFETs' minimum on resistance. The MAX4426/MAX4427/MAX4428's high speed minimizes power losses in switching power supplies and DC-DC converters.ApplicationsCharge-Pump Voltage InvertersDC-DC ConvertersMotor ControllersPin-Diode DriversSwitching Power Supplies

The MAX44285 dual-channel high-side current-sense amplifier has precision accuracy specifications of VOSless than 10µV (max) and gain error less than 0.1% (max).The MAX44285 features an input common-mode voltage range from 2.7V to 76V with 80kHz of small-signal bandwidth, which makes it ideal for interfacing with a SAR ADC for multichannel multiplexed data acquisition systems.The MAX44285 operates over the -40°C to +125°C temperature range. The MAX44285 is offered in 8-bump WLP and 8-pin µMAX®packages.ApplicationsBase Stations and Communication EquipmentIndustrial Control and AutomationPower Management SystemsServer Backplanes
