Description

The TEA1062 and TEA1062AT/C4,112 are integrated circuits thatperform 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. TEA1062AT/C4,112 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 electretmicrophones• 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 orpiezoelectric earpieces• Large gain setting ranges on microphone and earpieceamplifiers• Line loss compensation (line current dependent) for microphone and earpiece amplifiers• Gain control curve adaptable to exchange supply• DC line voltage adjustment facility
