a loudspeaker during on-hook dialling. The TEA1083/83A is intended for use in conjunction with a transmission circuit of the TEA1060 family. The device uses a part of the available line current via the internal supply circuit. The loudspeaker amplifier, which consists of a preamplifier and a power amplifier, amplifies the received line signals from the transmission circuit when enabled via the LS……
