GENERAL DESCRIPTION
The TEA1094 and TEA1094A are bipolar circuits intended
for use in mains, battery or line-powered telephone sets,
cordless telephones, answering machines and Fax
machines. In conjunction with a member of the TEA106X,
TEA111X families of transmission circuits, the devices
offer a hands-free function. They incorporate a
microphone amplifier, a loudspeaker amplifier and a
duplex controller with signal and noise monitors on
both channels.
