Rail-to-Rail Input S tage
The MAX4040–MAX4044 have rail-to-rail inputs and
rail-to-rail output stages that are specifically designed
for low-voltage, single-supply operation. The input
stage consists of separate NPN and PNP differential
stages, which operate together to provide a common-
mode range extending to both supply rails. The
crossover region of these two pairs occurs halfway
between V
CC
and V
EE
. The input offset voltage is typi-
cally 200μV. Low operating supply voltage, low supply
current, rail-to-rail common-mode input range, and rail-
to-rail outputs make this family of operational amplifiers
an excellent choice for precision or general-purpose,
low-voltage battery-powered systems.
Since the input stage consists of NPN and PNP pairs,
the input bias current changes polarity as the common-
mode voltage passes through the crossover region.
Match the effective impedance seen by each input to
reduce the offset error caused by input bias currents
flowing through external source impedances (Figures
1a and 1b). The combination of high source impedance
plus input capacitance (amplifier input capacitance
plus stray capacitance) creates a parasitic pole that
produces an underdamped signal response. Reducing
input capacitance or placing a small capacitor across
the feedback resistor improves response in this case.
