GENERAL DESCRIPTION
The TEA1114A is a bipolar integrated circuit that performs
all speech and line interface functions required in fully
electronic telephone sets. It performs electronic switching
between speech and dialling. The IC operates at a line
voltage down to 1.45 V DC (with reduced performance) to
facilitate the use of telephone sets connected in parallel.
When the line current is high enough, a fixed amount of
current is derived from the LN pin in order to create a
strong supply point at pin VDD. The voltage at pin VDD is
regulated to 3.3 V to supply peripherals such as dialler,
LCD module and microcontroller.
