TEA1062  -Low voltage transmission circuits with dialler interface

GENERAL DESCRIPTION

The TEA1062 and TEA1062A are integrated circuits that

perform all speech and line interface functions required in

fully electronic telephone sets. They perform electronic

switching between dialling and speech. The ICs operate at

line voltage down to 1.6 V DC (with reduced performance)

to facilitate the use of more telephone sets connected in

parallel.

All statements and values refer to all versions unless

otherwise specified.

FEATURES

• Low DC line voltage; operates down to 1.6 V (excluding

polarity guard)

• Voltage regulator with adjustable static resistance

• Provides a supply for external circuits

• Symmetrical high-impedance inputs (64 kΩ) for

dynamic, magnetic or piezoelectric microphones

• Asymmetrical high-impedance input (32 kΩ) for electret

microphones

• DTMF signal input with confidence tone

• Mute input for pulse or DTMF dialling

– TEA1062: active HIGH (MUTE)

– TEA1062A: active LOW (MUTE)

• Receiving amplifier for dynamic, magnetic or

piezoelectric earpieces

• Large gain setting ranges on microphone and earpiece

amplifiers

• Line loss compensation (line current dependent) for

microphone and earpiece amplifiers

• Gain control curve adaptable to exchange supply

• DC line voltage adjustment facility
