Low-Cost, High-Speed, SOT23, Single-Supply
Op Amps with Rail-to-Rail Outputs
_______________General Description
The MAX4012 single, MAX4016 dual, MAX4018 triple,
and MAX4020 quad op amps are unity-gain-stable
devices that combine high-speed performance with
Rail-to-Rail® outputs. The MAX4018 has a disable fea-
ture that reduces power-supply current to 400µA and
places its outputs into a high-impedance state. These
devices operate from a +3.3V to +10V single supply or
from ±1.65V to ±5V dual supplies. The common-mode
input voltage range extends beyond the negative
power-supply rail (ground in single-supply applica-
tions).
These devices require only 5.5mA of quiescent supply
current while achieving a 200MHz -3dB bandwidth and
a 600V/µs slew rate. These parts are an excellent solu-
tion in low-power/low-voltage systems that require wide
bandwidth, such as video, communications, and instru-
mentation. In addition, when disabled, their high output
impedance makes them ideal for multiplexing applica-
tions.
The MAX4012 comes in a miniature 5-pin SOT23 pack-
age, while the MAX4016 comes in 8-pin µMAX and SO
packages. The MAX4018/MAX4020 are available in a
space-saving 16-pin QSOP, as well as a 14-pin SO.

Op Amps with Rail-to-Rail Outputs
Maxim recommends using microstrip and stripline tech-
niques to obtain full bandwidth. To ensure that the PC
board does not degrade the amplifier’s performance,
design it for a frequency greater than 1GHz. Pay care-
ful attention to inputs and outputs to avoid large para-
sitic capacitance. Whether or not you use a constant-
impedance board, observe the following guidelines
when designing the board:
• Don’t use wire-wrap boards because they are too
inductive.
• Don’t use IC sockets because they increase parasitic
capacitance and inductance.
• Use surface-mount instead of through-hole compo-
nents for better high-frequency performance.
• Use a PC board with at least two layers; it should be
as free from voids as possible.
• Keep signal lines as short and as straight as possi-
ble. Do not make 90° turns; round all corners.
Rail-to-Rail Outputs,
Ground-Sensing Input
The input common-mode range extends from
(VEE - 200mV) to (VCC - 2.25V) with excellent common-
mode rejection. Beyond this range, the amplifier output
is a nonlinear function of the input, but does not under-
go phase reversal or latchup.
The output swings to within 60mV of either power-
supply rail with a 2kΩ load. The input ground-sensing
and the rail-to-rail output substantially increase the
dynamic range. With a symmetric input in a single +5V
application, the input can swing 2.95Vp-p, and the out-
put can swing 4.9Vp-p with minimal distortion.
Enable Input and Disabled Output
The enable feature (EN_) allows the amplifier to be
placed in a low-power, high-output-impedance state.
Typically, the EN_ logic low input current (IIL) is small.
However, as the EN voltage (VIL) approaches the nega-
tive supply rail, IIL increases (Figure 2). A single resis-
tor connected as shown in Figure 3 prevents the rise in
the logic-low input current. This resistor provides a
feedback mechanism that increases VIL as the logic
input is brought to VEE. Figure 4 shows the resulting
input current (IIL).
When the MAX4018 is disabled, the amplifier’s output
impedance is 35kΩ. This high resistance and the low
2pF output capacitance make this part ideal in
RF/video multiplexer or switch applications. For larger
arrays, pay careful attention to capacitive loading. See
the Output Capacitive Loading and Stability section for
more information.
