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 2k
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 35k
. 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.
