Notes
1. Mostly dependent on the maximum required Tamb and on the voltage between LN and SLPE (see Fig.26 for TEA1069N or Fig.27 for TEA1069H and TEA1069AH).
2. Calculated for the maximum specified ambient temperature (Tamb = 70 °C, see also Fig.26 for TEA1069N or Fig.27 for TEA1069H and TEA1069AH).


Description

The TEA1069 and TEA1069A contain all the functions needed to build a highly featured, high-performance fully electronic telephone set.

The device incorporates a speech/transmission part, a dialler part and a ringer part. By offering a wide range of possible adaptations for each part, the TEA1069 and TEA1069A application can be easily adapted to meet different requirements.

The TEA1069A offers some different timings and diode options compared to the TEA1069. Where pin numbers are mentioned in this data sheet we refer to the TEA1069N, unless otherwise indicated.
