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.
