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