General Description
The TEA1064A is a bipolar integrated circuit that performs all the speech and line interface functions required in fully electronic telephone sets.
It performs electronic switching between dialling and speech and has a powerful DC supply for peripheral circuits.
Key Features
- Low DC line voltage; operates down to 1.8 V (excluding polarity guard).
- Voltage regulator with low voltage drop and adjustable static resistance.
- DC line voltage adjustment facility.
- Provides a supply for external circuits in two options: unregulated supply, regulated line voltage; stabilized supply, line voltage varies with supply current.
- Dynamic limiting (speech-controlled) in transmit direction prevents distortion of line signal and sidetone.
