Communication ICs Pseudo inductance for telephones BA8201 / BA8201F The BA8201 and BA8201F are ICs with a choke coil action, capable of extracting the DC current from a telephone line while maintaining a high inductance on the telephone line side.
This eliminates the need for a choke coil, and facilitates use of the telephone set line in a variety of applications.
FApplications Household telephones FFeatures 1) Corresponds to choke coil of several henries.
2) Extracts DC current while maintaining high inductance on telephone line side.
3) Capable of extracting large output current.
4) Wide dynamic range.
5) Two output voltage modes available for selection.
S Line voltage seek mode S Cons...
