TEA1062; TEA1062A
Information as of 2000-08-19
TEA1062; TEA1062A; Low voltage transmission circuits with dialler interface
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.
l
Low DC line voltage; operates down to 1.6 V (excluding polarity guard)
l
Voltage regulator with adjustable static resistance
l
Provides a supply for external circuits
l
Symmetrical high-impedance inputs (64 k
) for dynamic, magnetic or piezoelectric microphones
l
Asymmetrical high-impedance input (32 k
) for electret microphones
l
DTMF signal input with confidence tone
l
Mute input for pulse or DTMF dialling
- TEA1062: active HIGH (MUTE)
- TEA1062A: active LOW (MUTE)
l
Receiving amplifier for dynamic, magnetic or piezoelectric earpieces
l
Large gain setting ranges on microphone and earpiece amplifiers
l
Line loss compensation (line current dependent) for microphone and earpiece amplifiers
l
Gain control curve adaptable to exchange supply
l
DC line voltage adjustment facility.
