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.

Features
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.
