• Manufacturer Part Number: MAX4036
• Description: The single MAX4036/MAX4037 and dual MAX4038/MAX4039 operational amplifiers operate from a single +1
• Manufacturer: Maxim

The MAX4036–MAX4039 consume an ultra-low supply
current and have rail-to-rail output stages specifically
designed for low-voltage operation. The input common-
mode voltage range extends from V
although full rail-to-rail input range is possible with
degraded performance when operating from a supply
voltage above 3.0V. The input offset voltage is typically
200µV. Low-operating supply voltage, low supply current,
and rail-to-rail outputs make the MAX4036–MAX4039 an
excellent choice for precision or general-purpose low-
voltage, battery-powered systems.
The MAX4036–MAX4039 output stages can drive a 5kΩ
load and still swing to within 40mV of the rails. Figure 1
shows the output voltage swing of the MAX4036–
MAX4039 configured as a unity-gain buffer, powered
from a single 2.4V supply. The output for this setup typi-
cally swings from 5mV to V
