The MAX44265EWT+T is a rail-to-rail, 200KHz operational amplifier with shutdown in 6 pin WLP package. The MAX44265 op amp features a maximized ratio of gain bandwidth (GBW) to supply current and is ideal for battery-powered applications such as handsets, tablets, notebooks and portable medical equipment. This CMOS op amp features an ultra-low input-bias current of 1pA, rail-to- rail input and output, low supply current of 4µA and operates from a single 1.8V to 5.5V supply. For additional power conservation, the IC also features a low-power shutdown mode that reduces supply current to 1nA and puts the amplifier"s outputs in a high-impedance state. This device is unity-gain stable with a 200KHz GBW product.
