ADC Input Buffer
Input buffer amplifiers can be a source of significant
errors in high-speed analog-to-digital converter (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 con-
version cycle, measurement accuracy must be main-
tained 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 overload makes the MAX4412/
MAX4413 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 +5.5V
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 capacitances at inputs and out-
puts. Whether or not a constant-impedance board is
used, observe the following guidelines:
Do not use wire-wrap boards due to their high induc-
tance.
Do not use IC sockets because of the increased par-
asitic 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 possible.
Do not make 90
°
turns; round all corners.
