MAX44265:Rail-to-Rail, 200kHz Op Amp with Shutdown in a Tiny, 6-Bump WLP

Save Power and Board Space—Op Amp Consumes Only 4µA and Offers 200kHz BW in 0.4mm Pitch 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. It is available in a space-saving, 0.9mm x 1.3mm, 6-bump WLP package and is specified over the -40°C to +85°C extended operating temperature range.
