Tone ringer IC for telephone set

BA8206 / BA8206F

The BA8206 and BA8206F are tone ringer ICs which produce a bell sound from a ringing signal. The frequency of the

bell sound can be varied by changing the constants of the external resistance and capacitors.

The operation initiation current dissipation can be changed at the RSL pin.

Also, the output load can be selected, as a piezoelectric buzzer, a transformer coupled speaker, or other similar devices.

FApplications

Telephones, multi-function telephones, telephone answering machines, facsimiles, equipment involving telephones

FFeatures

1) Low current dissipation.

2) Withstands up to 40V.

3) Operation initiation current dissipation can be

changed using RSL pin.

4) Pin layout is compatible with the BA8205, BA6565A,

and ML8205.
