GENERAL DESCRIPTION
The TEA1066T is a bipolar integrated circuit that performs
all speech and line interface functions required in fully
electronic telephone sets. The circuit performs electronic
switching between dialling and speech.
PACKAGE
Receiving amplifier for magnetic, dynamic or
piezoelectric earpieces
Large gain setting range on microphone and earpiece
amplifiers
Line loss compensation facility, line current dependent
(microphone and earpiece amplifiers)
Gain control adaptable to exchange supply
DC line voltage adjustment facility.
