General Description

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 cur-

rent of 1pA, rail-to- rail input and output, low supply cur-

rent 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 sup-

ply 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.
