TEA1114A Low Voltage Telephone Transmission Circuit With Dialler Interface And Regulated Strong Supply

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
