Evaluation Board Information
A data sheet is available for the CLC730038/CLC730036
evaluation boards. The evaluation board data sheets pro-
vide:
The evaluation boards are designed to accommodate dual
supplies. The boards can be modified to provide single
supply operation. For best performance; 1) do not connect
the unused supply, 2) ground the unused supply pin.
Special Evaluation Board Considerations for the
CLC5632
To optimize off-isolation of the CLC5632, cut the R
both the CLC730038 and the CLC730036 evaluation
boards. This cut minimizes capacitive feedthrough between
the input and the output. Figure 13 shows where to cut both
evaluation boards for improved off-isolation.
• Remove the ground plane under and around the part,
• Minimize all trace lengths to reduce series inductances.
• Use flush-mount printed circuit board pins for prototyping,
• Evaluation board schematics
• Evaluation board layouts
• General information about the boards
especially near the input and output pins to reduce para-
sitic capacitance.
never use high profile DIP sockets.

SPICE Models
SPICE models provide a means to evaluate amplifier de-
signs. Free SPICE models are available for National’s mono-
lithic amplifiers that:
The readme file that accompanies the diskette lists released
models, and provides a list of modeled parameters. The
application note OA-18, Simulation SPICE Models for Na-
tional’s Op Amps, contains schematics and a reproduction of
the readme file.

Single Supply Cable Driver
Figure 14 below shows the CLC5632 driving 10m of 75
coaxial cable. The CLC5632 is set for a gain of +2V/V to
compensate for the divide-by-two voltage drop at V
response after 10m of cable is illustrated in Figure 15
• Support Berkeley SPICE 2G and its many derivatives
• Reproduce typical DC, AC, Transient, and Noise perfor-
• Support room temperature simulations
