Miniature, 300MHz, Single-Supply,
Rail-to-Rail Op Amps with Enable
General Description
The MAX4212/MAX4213 single, MAX4216 dual,
MAX4218 triple, and MAX4220 quad op amps are
unity-gain-stable devices that combine high-speed per-
formance with rail-to-rail outputs. The MAX4213/
MAX4218 have a disable feature that reduces power-
supply current to 400µA and places the 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 applications).
These devices require only 5.5mA of quiescent supply
current while achieving a 300MHz -3dB bandwidth and
a 600V/µs slew rate. Input voltage noise is only
10nV/√Hz and input current noise is only 1.3pA/√Hz for
either the inverting or noninverting input. These parts
are an excellent solution in low-power/low-voltage sys-
tems that require wide bandwidth, such as video, com-
munications, and instrumentation. In addition, when
disabled, their high output impedance makes them
ideal for multiplexing applications.
The MAX4212 comes in a miniature 5-pin SOT23 pack-
age, while the MAX4213/MAX4216 come in 8-pin µMAX
and SO packages. The MAX4218/MAX4220 are avail-
able in a space-saving 16-pin QSOP, as well as a
14-pin SO.

Miniature, 300MHz, Single-Supply,
Rail-to-Rail Op Amps with Enable
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 50mV of either power-
supply rail with a 10kΩ 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 MAX4213/MAX4218 are disabled, the amplifi-
er’s output impedance is 35kΩ. This high resistance
and the low 2pF output capacitance make these parts
ideal in RF/video multiplexer or switch applications. For
larger arrays, pay careful attention to capacitive load-
ing. See the Output Capacitive Loading and Stability
section for more information.
