Connects a high-pass filter to the offset control loop
pin. This jumper is normally not installed.
Disables the offset correction loop. This jumper is
installed for dc or low frequency operation.
Mode up. Install for ascending gain with increasing
VDBS gain control voltage.
Mode down. Install for descending gain with
increasing VDBS gain control voltage.

MEASUREMENT SETUP
The basic board connections for a typical measurement are
shown in Figure 71. To minimize circuit-loading effects, a low
capacitance FET probe is recommended for observing input or
output waveforms. Two-pin headers, IN_TEST and OUT_TEST,
are provided for this purpose. The SMA connectors OUT_HI
and OUT_LO can also be used, but the user may need to
account for load capacitance effects.
AD8330-EVALZ BOARD DESIGN
The AD8330-EVALZ is a 4-layer design for maximum ground-
plane area. The evaluation board side silkscreen and wiring
patterns are shown in Figure 72 through Figure 77.
