♦ 5-Pin SOT23-5 Package (MAX4130)
♦ +2.7V to +6.5V Single-Supply Operation
♦ Rail-to-Rail Input Common-Mode Voltage Range
♦ Rail-to-Rail Output Voltage Swing
♦ 10MHz Gain-Bandwidth Product
♦ 900µA Quiescent Current per Amplifier
♦ 25µA Shutdown Function (MAX4131/MAX4133)
♦ 200µV Offset Voltage
The MAX4130–MAX4134 family of operational amplifiers
combines 10MHz gain-bandwidth product and excellent
DC accuracy with rail-to-rail operation at the inputs and
outputs. These devices require only 900µA per amplifier,
and operate from either a single supply (+2.7V to +6.5V)
or dual supplies (±1.35V to ±3.25V) with a common-
mode voltage range that extends 250mV beyond V
EE
and V . They are capable of driving 250Ω loads and
CC
a re unity-g a in s ta b le . In a d d ition, the MAX4131/
MAX4133 feature a shutdown mode in which the outputs
are placed in a high-impedance state and the supply
current is reduced to only 25µA per amplifier.
With their rail-to-rail input common-mode range and
output swing, the MAX4130–MAX4134 are ideal for low-
voltage, single-supply operation. Although the minimum
ope ra ting volta ge is sp e c ifie d a t 2.7V, the de vic e s
typically operate down to 1.8V. In addition, low offset
voltage and high speed make them the ideal signal-
conditioning stages for precision, low-voltage data-
a c q uis ition s ys te ms . The MAX4130 comes in the
space-saving SOT23-5 package.
♦ No Phase Reversal for Overdriven Inputs
♦ Drive 250Ω Loads
♦ Stable with 160pF Capacitive Loads
♦ Unity-Gain Stable

stages designed for low-voltage, single-supply opera-
tion. The input stage consists of separate NPN and
PNP differential stages that combine to provide an
input common-mode range that extends 0.2V beyond
the supply rails. The PNP stage is active for input volt-
ages close to the negative rail, and the NPN stage is
active for input voltages near the positive rail. The input
offset voltage is typically below 200µV. The switchover

(Figure 2). For differential input voltages less than 1.8V,
input resistance is typically 500kΩ. For differential input
voltages greater than 1.8V, input resistance is approxi-
mately 2kΩ. The input bias current is given by the fol-
lowing equation:
transition region, which occurs near V / 2, has been
CC
extended to minimize the slight degradation in com-
mon-mode rejection ratio caused by the mismatch of
the input pairs. Their low offset voltage, high band-
width, and rail-to-rail common-mode range make these
op amps excellent choices for precision, low-voltage
data-acquisition systems.

Since the input stage switches between the NPN and

Driving a capacitive load can cause instability in most

ground for single-supply operation where the load is
referenced to ground (V ). Figure 3 shows the input

voltage range and output voltage swing of a MAX4131
connected as a voltage follower. With a +3V supply
and the load tied to ground, the output swings from
0.00V to 2.90V. The maximum output voltage swing
depends on the load, but will be within 150mV of a +3V
supply, even with the maximum load (500Ω to ground).

Good layout improves performance by decreasing the
amount of stray capacitance at the op amp’s inputs
and outputs. Decrease stray capacitance by placing
external components close to the op amp’s pins, mini-
mizing trace lengths and resistor leads.

The MAX4130–MAX4134 operate from a single +2.7V
to +6.5V power supply, or from dual supplies of ±1.35V
to ±3.25V. For single-supply operation, bypass the
power supply with a 0.1µF ceramic capacitor in parallel
with at least 1µF. For dual supplies, bypass each sup-
ply to ground.
