Product specification
Versatile telephone transmission circuit
with dialler interface
TEA1068
FEATURES
Voltage regulator with adjustable static resistance
Provides supply for external circuitry
Symmetrical high-impedance inputs (64 k
) for
dynamic, magnetic or piezoelectric microphones
Asymmetrical high-impedance input (32 k
) for electret
microphone
Dual-Tone Multi-Frequency (DTMF) signal input with
confidence tone
Mute input for pulse or DTMF dialling
Power down input for pulse dial or register recall
Receiving amplifier for magnetic, dynamic or
piezoelectric earpieces
Large gain setting range on microphone and earpiece
amplifiers
Line current-dependent line loss compensation facility
for microphone and earpiece amplifiers
Gain control adaptable to exchange supply
DC line voltage adjustment facility.
GENERAL DESCRIPTION
The TEA1068 is a bipolar integrated circuit performing all
speech and line interface functions required in fully
electronic telephone sets. It performs electronic switching
between dialling and speech.
