AD8436
The AD8436-EVALZ provides a platform to evaluate
performance. The board is fully assembled, tested and ready to
use after the power and signal sources are connected. Figure 45
is a photograph of the board. Signal connections are located
on the primary and secondary sides, with power and ground
on the inner layers. Figure 40, Figure 41, Figure 42, Figure 43,
and Figure 44 illustrate the various design details of the board,
including a basic layout and copper patterns. These figures are
useful for reference for application designs.
A Word About Using the AD8436 Evaluation Board
The AD8436-EVALZ offers many options, without sacrificing
simplicity. The board is tested and shipped with a 10 μF averaging
capacitor (CAVG), 3.3 μF low-pass filter capacitor (C8) and a
0.1 μF (COPT) capacitor to optimize crest factor performance.
To evaluate minimum cost applications, remove C8 and COPT.
The functions of the five switches are listed in Table 6.

All the I/Os are provided with test points for easy monitoring
with test equipment. The input buffer gain default is unity; for
2× gain, install a 0603 0 Ω resistor at Position R5. For higher
IBUF gains, remove the 0 Ω resistor at Position RFBH (there is
an internal 10 kΩ resistor from the OBUF_OUT to IBUFIN−)
and install a smaller value resistor in Position RFBL. A 100 Ω
resistor establishes a gain of 100×.
Single supply operation requires removal of Resistor R6 and
installing a 0.1 μF capacitor in the same position for noise
decoupling.
