GENERAL DESCRIPTION
The TEA1095 is a bipolar circuit, that in conjunction with a
member of the TEA106X, TEA111X families of
transmission or TEA1096 transmission/listening-in circuits
offers a hands-free function. It incorporates a transmit
amplifier, a receiver channel amplifier and a duplex
controller with signal and noise monitors on both channels.
