BA8201 Datasheet Pseudo Inductance For Telephones

Manufacturer: ROHM

Overview: 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.

General Description

s BA8201 / BA8201F 302 Communication ICs BA8201 / BA8201F FElectrical characteristics (unless otherwise noted, Ta = 25_C, VLN = 4V, υLN = 100mVrms, Io = 5mA, f = 1kHz) FMeasurement circuits 303 Communication ICs BA8201 / BA8201F 304 Communication ICs FApplication example BA8201 / BA8201F FAttached components C1: This is a capacitor for phase compensation, and is normally connected at 68pF.

C2: This is a coupling capacitor.

The inductance from the telephone line changes based on this value.
