The MAX4289 micropower, operational amplifier is opti-
mized for ultra-low supply voltage operation. The ampli-
fier consumes only 9µA of quiescent supply current and
is fully specified for operation from a single 1.0V to 5.5V
power supply. This ultra-low voltage operation together
with the low quiescent current consumption make the
MAX4289 ideal for use in battery-powered systems
operated from as little as a single alkaline cell. The
MAX4289 also features a wide input common-mode
range that includes the ground, and an output voltage
swing that is virtually Rail-to-Rail
the power supply to be used for signal voltage.
The low input offset voltage and low input bias current
specifications along with the high open-loop gain make
the MAX4289 well-suited to applications requiring a
high degree of precision.
The MAX4289 is available in a tiny 6-pin SOT23 pack-
age. All specifications are guaranteed over the extend-
ed temperature range of -40°C to +85°C.
