    Figure 17, the Reference-Adjust Circuit, shows how to
    adjust ADC gain in applications that use the internal
    reference. The circuit provides ±1.5% (±16LSBs) of
    gain-adjustment range.
    Layout, Grounding, Bypassing
    For best performance, use printed circuit boards.
    Wire-wrap boards are not recommended. Board layout
    should ensure that digital and analog signal lines are
    separated from each other. Do not run analog and digital
    (especially clock) lines parallel to one another, or digital
    lines underneath the ADC package.
    Figure 18 shows the recommended system-ground con-
    nections. Establish a single-point analog ground (star
    ground point) at GND. Connect all other analog grounds
    to this ground. No other digital system ground should be
    connected to this single-point analog ground. The
    ground return to the power supply should be low imped-
    ance and as short as possible for noise-free operation.
    High-frequency noise in the V
    DD
    power supply may affect
    the high-speed comparator in the ADC. Bypass these
    supplies to the single-point analog ground with 0.1μF and
    4.7μF bypass capacitors close to the MAX1204. Minimize
    capacitor lead lengths for best supply-noise rejection. If
    the +5V power supply is very noisy, a 10
    resistor can
    be connected as a lowpass filter, as shown in Figure 18.
