Application Information
A typical application circuit for the CLC021 is shown in Fig-
ure 6 This circuit demonstrates the capabilities of the
CLC021 and allows its evaluation in a variety of configura-
tions. Assembled demonstration boards with more compre-
hensive evaluation options are available, part number
SD021-5EVK (5V device) or SD021-3EVK (3.3V device).
The boards may be ordered through any of National’s sales
offices. Complete circuit board layouts and schematics in-
cluding Gerber photoplot files, for the demonstration boards
are available on National’s WEB site in the application infor-
mation for this device. For latest information, please see:
