Single/Dual/Quad / Low-Cost / SOT23 / Micropower Rail-to-Rail I/O Op Amps
________________General DescriptionThe MAX4040–MAX4044 family of micropower op amps
operates from a single +2.4V to +5.5V supply or dual
±1.2V to ±2.75V supplies and have Rail-to-Rail®input
and output capabilities. These amplifiers provide a
90kHz gain-bandwidth product while using only 10µA of
supply current per amplifier. The MAX4041/MAX4043
have a low-power shutdown mode that reduces supply
current to less than 1µA and forces the output into a
high-impedance state. The combination of low-voltage
operation, rail-to-rail inputs and outputs, and ultra-low
power consumption makes these devices ideal for any
portable/battery-powered system.
These amplifiers have outputs that typically swing to
within 10mV of the rails with a 100kΩload. Rail-to-rail
input and output characteristics allow the full power-
supply voltage to be used for signal range. The combi-
nation of low input offset voltage, low input bias current,
and high open-loop gain makes them suitable for low-
power/low-voltage precision applications.
The MAX4040 is offered in a space-saving 5-pin SOT23
package. All specifications are guaranteed over the
-40°C to +85°C extended temperature range.

_______________Detailed Description
Rail-to-Rail Input StageThe 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 VCCand VEE. 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.
