AD637
EVALUATION BOARD
The evaluation board for the AD637 is shown in Figure 23. It is
available at
www.analog.com
and ships fully tested and ready
for bench testing by just adding power and signal connections.
The circuit is configured for dual power supplies, and standard
BNC connectors serve as the signal input and output ports.
Referring to the schematic in
Figure 29
, the input BNC
RMS_IN is capacitively coupled to Pin 15 V
of the AD637.
IN
The BNC connector DC_OUT is connected to Pin 11, RMS
OUT, with provisions for connections to the output buffer
between Pin 1 and Pin 16. Users can connect the buffer using
components of their choice. A trimmer is available for adjusting
the output offset voltage. The board contains provisions for one
or two poles of low-pass filtering using CF1, CF2, R4, and R5.
See Figure 24 to locate these components.
