Figure 56 is a photograph of the AD604 evaluation board assembly.
Multiple input connections, testpoints, switch-selectable options,
and on-board trims offer convenience when configuring the
AD604 in various operating modes.
The evaluation board requires only a dual 5 V supply capable of
200 mA or higher to operate both channels. Prior to shipment,
the evaluation board is fully tested. Users need only attach power
supply leads and the appropriate test equipment to the board.
Because of this flexibility, some of the component positions on
the board are user selectable. Installing or changing additional
parts, such as gain resistor values or SMA connectors for non-
standard I/O, is discretionary.
The AD604-EVALZ is fabricated on a 4-layer board with inner
power and ground layers. Figure 55 is a photograph of the top
views of the board, assembly and artwork layers are shown in
Figure 56, a representative test setup is shown in Figure 57, and
evaluation board.

DSX INPUT CONNECTIONS
The VGA input configuration options are single-ended or
differential. Connections are provided for each of the inputs and
are labeled VGAx+IN and VGAxIN. Switches VGAx+IN and
VGAxIN select between the preamplifier outputs (PAOx) and
the VGA SMA input connectors. For direct drive of the Channel
VGA channels from an external source, such as a signal generator,
simply use the switches to select the desired signal paths. Refer
to the schematic shown in Figure 63 for circuit details.
Because the VGA section of the AD604 uses a single 5 V supply,
the VGA inputs are ac-coupled. The VGA ladder network input is
connected to the device ±DSX1/±DSX2 pins, and the network
impedance is nominally 200 Ω. If direct access to the DSX is
desired, signals can be applied to the test loops ±DSX1/±DSX2.
Optionally, SMA connectors can be installed at the VGAx±IN
locations and 66.5 Ω, 1% resistors at R5, R6, R9, and R10 to
provide an input termination value of 49.9Ω.
Cascade VGAs to Boost Gain
Figure 55. Top View Photograph of AD604 Evaluation Board
The AD604 channels may be cascaded to achieve higher gain
range by moving the VG2+IN_SW to its CASCADE position.
The resulting single-channel gain range is 96 dB.
CONNECTING A WAVEFORM TO THE AD604-EVALZ
To test the AD604, apply the desired waveform to either or both
of the preamplifier input SMA connectors, PRE1IN or PRE2IN.
Referring to the schematic in Figure 63, the inputs are already
terminated 49.9 Ω resistors (R7 and R8); therefore, no external
terminating networks are required.
The gains of cascaded VGAs are controlled independently or in
common. For common (parallel) control, move the gain control
switch, GN2, to the 1&2 position.
To use the optional GNx_ADJ trimmers for static gain control
voltages, set GN1 to EXT and GN2 to 2ONLY. For external
control, connect the desired signal source to the test loops, VGNx.
To enable the preamplifiers, insert jumpers in the JP8 and JP9
rightmost positions; this connects COM1 and COM2 to ground.
Power down the preamplifiers by inserting jumpers in the JP8
and JP9 leftmost positions.
