Single/Dual/Quad High-Speed, Fast-Settling,
High Output Current Operational Amplifier
Features
The MAX408/428/448 are high speed general purpose
monolithic operational amplifiers in a single, dual or
quad package, that are useful for signal frequencies
extending into the video range. These Op Amps function in gain configurations greater-than or equal-to 3.
High output current allows large capacitive loads to be
driven at high speeds.
♦ Fast Settling Time: ±0.1% In 150ns
♦ High Slew Rate: 90V/µs
♦ Large Gain Bandwidth: 100MHz
♦ Full Power Bandwidth: 4.8MHz at 6V p-p
♦ Ease of Use: Internally Compensated for
ACL ≥ 3 with 50°–60° Phase Margin
Open-loop voltage gain of 10k V/V and high slew rate of
90V/µs make the MAX408/428/448 ideal for analog
amplification and high speed signal processing. 100MHz
gain bandwidth and a ±0.1% settling time of l50ns make
each amplifier ideal for fast data conversion systems.
The amplifiers are capable of driving back terminated
transmission lines of 75Ω with amplitudes of 5V peakto-peak.
Along with the high speed and output drive capability,
a 35nA offset current and trimmable offset voltage
make the MAX408/428/448 optimal for signal conditioning applications where accuracy must be maintained.
♦ Low Supply Voltage Operation: ±4V
♦ Wide Input Voltage Range: Within 1.5V of V+ and
0.5V of V♦ Minimal Crosstalk: >90dB Separation
(MAX428/448)
♦ Short Circuit Protection

Figure 1B. Large Signal Response
The 35MHz 10dB crossover point of the MAX408/
428/448 is achieved without feed forward compensation, a technique which can produce long tails in the
recovery characteristic. The single pole rolloff follows
the classic 20dB/decade slope to frequencies
approaching 50MHz. The 10dB (3.2V/V) phase margin
of 50°, even with a capacitive load of 50pF, gives stable
and predictable performance down to non-inverting
gain configurations of approximately 3V/V (inverting
gains of -2V/V). At frequencies beyond 50MHz, the
20dB/decade slope is disturbed by an output stage
zero, the damping factor of which is dependent upon
the RL, CL load combination. This results in loss of gain

margin (gain at loop phase = 360°) at frequencies of 70
to 100MHz which at a gain margin of 5dB (RL = 2k, CL
= 5pF) results in a peak in the gain of 3 amplifier configurations as shown in Figures 3 and 4.
Figure 3 shows a blow up of the open loop characteristics in the 10MHz to 200MHz frequency range, as well
as the corresponding closed loop characteristics for a
gain of three non-inverting amplifier at similar load conditions. It should be noted that the open loop characteristic does not show the additional phase shift covered
by the input capacitance pole. This is why the closed
loop peaking at 30 to 40MHz is greater than what
would be expected from the 50 to 60 degrees of phase
margin indicated by the open loop characteristics.
Corresponding small signal step response characteristics show well-behaved pulse waveforms with 16–33%
overshoot.
The input capacitive pole can be neutralized by adding
a feedback capacitor to R2. The value of capacitance
is selected according to R1 CIN = R2CFB, where CIN is
the sum of the common mode and differential input
capacitance ≈5pF. For R2 = 2R1, CFB = CIN/2 ≈ 2.5pF.
Figure 4 shows the results of this feedback capacitor
addition. Neutralizing the input capacitance demonstrates the peaking that can result from the loss of gain
margin at 70 to 100MHz. As the load time constant
(RLCL) increases the peaking gets progressively worse
≈6dB at RL = 2K, CL = 50pF. The step response waveforms are as expected with a very strong 88MHz ring
being exhibited at RL = 2k, CL = 50pF and no overshoot at RL = 50Ω, CL = 5pF.
Layout Considerations
As with any high-speed wideband amplifier, certain layout considerations are necessary to ensure stable operation. All connections to the amplifier should remain as
short as possible, and the power supplies bypassed with
0.1µF capacitors to signal ground. It is suggested that a
ground plane be considered as the best method for
ensuring stability because it minimizes stray inductance
and unwanted coupling in the ground signal paths.
To minimize capacitive effects, resistor values should be
kept as small as possible, consistent with the application.
MAX408 Offset Voltage Nulling
The configuration of Figure 2 will give a typical VOS
nulling range of ±15mV. If a smaller adjustment range is
desired, resistor values R1 and R2 can be increased
accordingly. For example, at R1 = 3.6kΩ, the adjustment
range is ±5mV. Since pins 1 and 5 are not part of the signal path, AC characteristics are left undisturbed.
