2. Application
In the application circuits shown below, the CPC5601
is used to switch AC termination and gain. Loop-cur-
rent limit switching is optional.

¹This design was tested and found to comply with FCC part 68 with this part.
Other compliance requirements may require a different part.
²Higher noise power supplies may require substitution of a 220 µH inductor,
Toko 380HB-2215 or similar. See the power quality section of Clare applica-
tion note AN-146, Guidelines for Effective LITELINK Designs for more informa-
tion. Both application circuits use the same components for setting AC
termination and the telephone line current limit.
