The MAX4289 consumes ultra-low power (9µA supply
current typically) and has a rail-to-rail output stage that
is specifically designed for low-voltage operation. The
input common-mode voltage range extends from V
0.2V to ground, although full rail-to-rail input range is
possible with degraded performance. The input offset
voltage is typically 200µV. Low-operating supply volt-
age, low supply current, and rail-to-rail outputs make
this operational amplifier an excellent choice for preci-
sion or general-purpose, low-voltage, battery-powered
systems.
The MAX4289 output stage can drive a 5kΩ load and
still swing to within 7mV of the rails. Figure 1 shows the
output voltage swing of the MAX4289 configured as a
unity-gain buffer, powered from a single 2V supply volt-
age. The output for this setup typically swings from
+0.4mV to (V
The MAX4289 operates from a single 1.0V to 5.5V supply
and consumes only 9µA of supply current. A high power-
supply rejection ratio of 75dB allows the amplifier to be
powered directly off a decaying battery voltage, simplify-
ing design and extending battery life. The MAX4289 is
ideally suited for single-cell battery-powered systems.
Figures 2 and 3 show the supply current and PSRR as a
function of supply voltage and temperature.
