TEA1062A Datasheet (NXP) - Low voltage transmission

TEA1062A, Low voltage transmission

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

TEA1062A 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
