Overview
Communication ICs Speech network BA6566 / BA6566F / BA6566FP 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 receivers, simply by changing the circuit constant for a wide dynamic reception range.
2) Automatic gain control (AGC) is used, based on the transmission and reception telephone line current, for easier compliance with communications standards.
FBlock diagram 3) Erroneous operation caused by high-frequency electrical wave interference is minimized.
4) An HSOP package is used, ...
