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 induc-
tance 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 Constant voltage mode
6) DIP 8 and SOP 8 pin packages available.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
