The BA6566, BA6566F, and BA6566FP are speech network ICs which possess the basic functions required for handset
communications. In addition to amplifying signals from a transmitter and sending them to a telephone line, they amplify
only reception signals from a telephone line and drive the receiver. They also compensate for fluctuation in the volume
at which signals are transmitted and received, caused by the length of the telephone line (AGC).
FApplications
Telephones and telephone equipment
FFeatures
1) Can accommodate both dynamic and piezoelectric
2) Automatic gain control (AGC) is used, based on the
