AD737 EVALUATION BOARD
An evaluation board, AD737-EVALZ, is available for experi-
ments or for becoming familiar with rms-to-dc converters.
Figure 33 is a photograph of the board; Figure 35 to Figure 38
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 39. 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

AD737 evaluation board.
