MAX44264EWT+T

运算放大器 - 运放 Ultra Low-Power

The is an ultra low power operational amplifier op-amp in 6 pin WLP package. This ultra small op-amp draws only 750nA of supply current. It operates from single 1.8V to 5.5V supply and features ground sensing inputs and rail to rail output. The ultra-low supply current, low operating voltage and rail to rail output capabilities make this operational amplifier ideal for use in single lithium ion Li+ or two cell NiCd or alkaline battery systems. The rail to rail output stage of MAX44264 is capable of driving the output voltage to within 4mV of rail with a 100Kohm load and can sink and source 11mA with 5V supply. The op-amp is unity gain stable.
