AD737 EVALUATION BOARD
An evaluation board, AD737-EVA L Z , is available for experi-
ments or for becoming familiar with rms-to-dc converters.
Figure 32 is a photograph of the board; Figure 34 to Figure 37
show the signal and power plane copper patterns. The board
is designed for multipurpose applications and can be used for
the AD736 as well. Although not shipped with the board, an
optional socket that accepts the 8lead surface-mount package
is available from Enplas Corp.

As described in the Applications Information section, the AD737
can be connected in a variety of ways. As shipped, the board is
configured for dual supplies with the high impedance input
connected and the power-down feature disabled. Jumpers are
provided for connecting the input to the low impedance input
(Pin 1) and for dc connections to either input. The schematic
with movable jumpers is shown in Figure 38. The jumper positions
in black are default connections; the dotted-outline jumpers are
optional connections. The board is tested prior to shipment and
requires only a power supply connection and a precision meter to
perform measurements.
