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.
FBlock diagram

4) Pin layout is compatible with the BA8205, BA6565A,
and ML8205.
