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.

Product Details

The MAX44265 evaluation kit (EV kit) provides a proven design to evaluate the MAX44265 low-power, MOS-input operational amplifier (op amp) in a 6-bump wafer-level package (WLP). The EV kit circuit is preconfigured as a noninverting amplifier, but can easily be adapted to other topologies by changing a few components. Low power, low-input V_OS, and rail-to-rail input/output stages make this device ideal for a variety of measurement applications. The component pads accommodate 0805 packages, making them easy to solder and replace. The EV kit comes with a MAX44265EWT+ installed.
