MAX402
The MAX402/MAX403/MAX438/MAX439 micropower op
amps combine high-speed performance with low-power
operation. The MAX402/MAX403 are compensated for
unity-gain stability, while the MAX438/MAX439 are com-
pensated for stability in applications with a closed-loop

gain (A ) of 5V/V or greater.
VCL
♦ 10MHz Unity-Gain Bandwidth
♦ 40V/µs Slew Rate
The MAX402/MAX438 require less than 75µA of supply
current while delivering 2MHz bandwidth with 6V/µs
slew rate (MAX402), and 6MHz gain bandwidth with
10V/µs slew rate (MAX438).
♦ 375µA Max Supply Current
MAX438
For a p p lic a tions re q uiring inc re a s e d s p e e d , the
MAX403/MAX439 consume less than 375µA of supply
current while delivering 10MHz gain bandwidth with
40V/µs slew rate (MAX403), and 25MHz gain bandwidth
with 48V/µs slew rate (MAX439).

Note 1: Absolute maximum ratings apply to packaged parts only, unless otherwise noted.
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.

The MAX402/MAX403/MAX438/MAX439 are specified
with ±5V power supplies, but also operate with dual
supplies down to ±3V or single supplies ranging from
+6V to +10V if the common-mode input voltage is kept
between (V- + 1.5V) and (V+ - 1.5V). With a single +6V
s up p ly, the c ommon-mod e inp ut volta g e ra ng e s
between +1.5V and +4.5V.

La yo u t a n d Byp a s s in g
Bypass the power-supply inputs with 0.1µF ceramic
capacitors positioned as close to the power-supply pins
as possible. To maximize performance in high-speed
applications, use a ground plane. Connections to the
amplifier’s input terminals should be as short and direct
as possible with a minimum of inductance and capaci-
tance. Stray capacitance at the input terminals adds to
the amplifier’s approximate 3pF input capacitance, and
can limit overall bandwidth. Also, minimize lead lengths
in connections from the power-supply bypass capacitors
to ground to further reduce inductance. Surface-mount
(chip) capacitors are ideal for this application.

The NULL pins (1 and 5) can be used to null the input
offset voltage. To adjust the amplifier’s offset voltage,
connect a potentiometer between the two NULL pins
with the wiper connected to V-, as shown in Figure 1.
Use a 10kΩ potentiometer with the MAX402/MAX438,
and a 2kΩ potentiometer with the MAX403/MAX439.
Offset voltage can be adjusted over a range of approxi-
mately 12mV with these trim potentiometers.
S le w Ra t e vs . In p u t Vo lt a g e
Like most high-speed op amps, the slew rate of the
MAX402/MAX403/MAX438/MAX439 depends on the
signal level driving the amplifier inputs. Slew-rate limit-
ing in high-speed circuits becomes more significant as
the amplifier’s closed-loop gain increases (inadequate
gain bandwidth is more likely to limit performance in
low-g a in c irc uits ). For this re a s on, the MAX438/
MAX439 have been characterized for slew rate vs.
input voltage, as shown in the MAX438/MAX439 Slew
Rate vs. Input Voltage graph in the Typical Operating
Characteristics.

Ove rlo a d Co n d it io n s
The amplifier inputs withstand differential voltages equal
to the power-supply rails without requiring external
clamp diodes or input current-limiting resistors. Schottky
diodes, used internally throughout the devices, prevent
saturation of the internal transistors and allow the ampli-
fiers to recover quickly from overload conditions.

Many op amps exhibit phase reversal at the output
whe n the inp ut c ommon-mod e volta g e ra ng e is
exceeded—a potentially serious problem in servo-con-
trol systems. Phase reversal protection circuitry in the
MAX402/MAX403/MAX438/MAX439 e limina te s this
problem for any input voltage level.

Each amplifier’s output stage employs a current-limit
circuit that prevents amplifier damage in the event of a
fault condition. The output may be shorted to either
power supply or ground continuously without damage.
