Active Filters
The low distortion and high bandwidth of the
MAX4452/MAX4453/MAX4454 and MAX4352/
MAX4353/MAX4354 make them ideal for use in active
filter circuits. Figure 4 is a 15MHz lowpass multiple
feedback active filter using the MAX4452.
ADC Input Buffer
Input buffer amplifiers can be a source of significant
errors in high-speed ADC applications. The input buffer
is usually required to rapidly charge and discharge the
ADC
s input, which is often capacitive. See
Output
Capacitive Loading and Stability
. In addition, since a
high-speed ADC
s input impedance often changes very
rapidly during the conversion cycle, measurement
accuracy must be maintained using an amplifier with
very low output impedance at high frequencies. The
combination of high speed, fast slew rate, low noise,
and a low and stable distortion over load makes the
MAX4452/MAX4453/MAX4454/MAX4352/MAX4353/
MAX4354 ideally suited for use as buffer amplifiers in
high-speed ADC applications.
Layout and Power-Supply Bypassing
These amplifiers operate from a single +2.7V to +5.25V
power supply. Bypass V
CC
to ground with a 0.1μF
capacitor as close to the pin as possible.
Maxim recommends using microstrip and stripline tech-
niques to obtain full bandwidth. Design the PC board
for a frequency greater than 1GHz to prevent amplifier
performance degradation due to board parasitics.
Avoid large parasitic capacitance at inputs and out-
puts. Whether or not a constant-impedance board is
used, observe the following guidelines:
Do not use wirewrap boards due to their high induc-
tance.
Do not use IC sockets because of the increased
parasitic capacitance and inductance.
