The MAX4490AUK+T is a single, high slew rate, rail to rail I/O operational amplifier (op-amp) in 5 pin SOT-23 package. This low cost CMOS op-amp has rail to rail input and output capability from either a single 2.7V to 5.5V supply or dual ±1.35V to ±2.75V supplies. This amplifier exhibits high slew rate of 10V/μs and gain bandwidth product of 10MHz. It can drive 2Kohm resistive loads to within 55mV of either supply rail and remain unity gain stable with capacitive loads up to 300pF. The MAX4490 is used in battery powered instruments, sensor amplifiers, RF power amplifiers control, high side/low side current sensors and low power/low voltage applications.
