TEA1097 Speech And Loudspeaker Amplifier IC With Auxiliary Inputs/outputs And Analog Multiplexer

The TEA1097 is an Analog bipolar circuit dedicated for telephone applications. It includes a line Interface handset Microphone and earpiece Amplifiers base Microphone and loudspeaker Amplifiers some specific auxiliary Inputs/Outputs (I/Os) and an Analog multiplexer to enable the right transmit and/or receive channels. The multiplexer is controlled by a Logic circuitry decoding four Logic inputs provided by a Microcontroller Twelve different application modes have been defined and CAN be accessed by selecting the right Logic inputs.This IC CAN be supplied by the line and/or by the mains if available (in a cordless telephone or a telephone answering machine for example). It provides a 3.35 V supply for a Microcontroller or dialler and a 2 V filtered voltage supply for electret Microphones The IC is designed to facilitate the use of the loudspeaker Amplifier during ringing phase.
