TEA1083; TEA1083A Call Progress Monitor For Line Powered Telephone Sets

The TEA1083 TEA1083A is a bipolar IC which has been designed for use in line powered telephone sets. It is intended to offer a monitoring facility of the line signal via 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 LSE input. The loudspeaker Amplifier CAN also be used to amplify dialling Tones from the dialler IC. The power Amplifier contains a push-pull output stage to drive the loudspeaker in a Single Ended Load (SEL) configuration. The internal voltage stabilizer CAN be used to supply external devices. By activating the power-down (PD) input of the TEA1083A the current consumption of the circuit will be reduced, this enables pulse dialling or Flash (register recall). An internal start circuit ensures normal start-up of the transmission IC.
