EVALUATION BOARD
An evaluation board, AD736-EVALZ, is available for
experimentation or becoming familiar with rms-to-dc converters.
Figure 29 is a photograph of the board, and Figure 30 is the top
silkscreen showing the component locations. Figure 31, Figure 32,
Figure 33, and Figure 34 show the layers of copper, and Figure 35
shows the schematic of the board configured as shipped. The board
is designed for multipurpose applications and can be used for the
AD737 as well.

As shipped, the board is configured for dual supplies and high
impedance input. Optional jumper locations enable low impedance
and dc input connections. Using the low impedance input (Pin 1)
often enables higher input signals than otherwise possible. A dc
connection enables an ac plus dc measurement, but care must
be taken so that the opposite polarity input is not dc-coupled
to ground.
Figure 35 shows the board schematic with all movable jumpers.
The jumper positions in black are default connections; the dotted-
outline jumpers are optional connections. The board is tested prior
to shipment and only requires a power supply connection and a
precision meter to perform measurements.
