MAX4130–MAX4134
Single/Dual/Quad, Wide-Bandwidth, Low-Power,
Single-Supply, Rail-to-Rail I/O Op Amps
General Description
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 commonmode voltage range that extends 250mV beyond VEE
and VCC. They are capable of driving 250Ω loads and
are unity-gain stable. In addition, 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 lowvoltage, single-supply operation. Although the minimum
operating voltage is specified at 2.7V, the devices
typically operate down to 1.8V. In addition, low offset
voltage and high speed make them the ideal signalconditioning stages for precision, low-voltage dataacquisition systems. The MAX4130 is offered in the
space-saving 5-pin SOT23 package. The MAX4131 is
offered in the ultra-small 6-bump, 1mm x 1.5mm chipscale package (UCSP™).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Applications Information
Rail-to-Rail Input Stage
Devices in the MAX4130–MAX4134 family of highspeed amplifiers have rail-to-rail input and output
stages designed for low-voltage, single-supply operation. 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 voltages 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
transition region, which occurs near VCC / 2, has been
extended to minimize the slight degradation in common-mode rejection ratio caused by the mismatch of
the input pairs. Their low offset voltage, high bandwidth, 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
PNP pairs, the input bias current changes polarity as
the input voltage passes through the transition region.
Reduce the offset error caused by input bias currents
flowing through external source impedances by matching the effective impedance seen by each input
(Figures 1a, 1b). High source impedances, together
with input capacitance, can create a parasitic pole that
produces an underdamped signal response. Reducing
the input impedance or placing a small (2pF to 10pF)
capacitor across the feedback resistor improves
response.
The MAX4130–MAX4134s’ inputs are protected from
large differential input voltages by 1kΩ series resistors
and back-to-back triple diodes across the inputs
(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 approximately 2kΩ. The input bias current is given by the following equation:
IBIAS =
VDIFF - 1.8V
2kΩ
1kΩ

Rail-to-Rail Output Stage
The minimum output voltage is within millivolts of
ground for single-supply operation where the load is
referenced to ground (VEE). 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).
Driving a capacitive load can cause instability in most
high-speed op amps, especially those with low quiescent current. The MAX4130–MAX4134 have a high tolerance for capacitive loads. They are stable with
capacitive loads up to 160pF. Figure 4 gives the stable
operating region for capacitive loads. Figures 5 and 6
show the response with capacitive loads and the
results of adding an isolation resistor in series with the
output (Figure 7). The resistor improves the circuit’s
phase margin by isolating the load capacitor from the
op amp’s output.

Power-Up and Shutdown Mode
The MAX4130–MAX4134 amplifiers typically settle within 1µs after power-up. Figures 9 and 10 show the output voltage and supply current on power-up, using the
test circuit of Figure 8.
The MAX4131 and MAX4133 have a shutdown option.
When the shutdown pin (SHDN) is pulled low, the supply current drops below 25µA per amplifier and the
amplifiers are disabled with the outputs in a highimpedance state. Pulling SHDN high or leaving it floating enables the amplifier. In the dual-amplifier
MAX4133, the shutdown functions operate independently. Figures 11 and 12 show the output voltage and
supply current responses of the MAX4131 to a shutdown pulse, using the test circuit of Figure 8.

Power Supplies and Layout
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 supply 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, minimizing trace lengths and resistor leads.
