Communication ICs Speech network for telephones BA6569AS / BA6569AFP The BA6569AS and BA6569AFP are speech networks which possesses the basic functions required for handset communications. In addition to amplifying signals from a transmitter and sending them to a telephone line, they also amplify only reception signals from a telephone line and drive the receiver. In addition to a function which compensates for fluctuation in the transmission and reception volume caused by the length of the telephone line (AGC), they are also equipped with a manual PAD function in order to accommodate PBX. FApplications Telephones and telephone equipment FFeatures 1) Basic speech network functions built in. 2) Single output pin of reception pre-amplifier is separate.
