Communication ICs 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. Applications Telephones, multi-function telephones, telephone answering machines, facsimiles, equipment involving telephones Features 1) Low current dissipation. 4) Pin layout is compatible with the BA8205, BA6565A, 2) Withstands up to 40V. and ML8205. 3) Operation initiation current dissipation can be changed using RSL pin.
