AD737 EVALUATION BOARD

An evaluation board, the AD737-EVALZ, 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.
