Information as of 2000-08-20
UBA2050(A); UBA2051(A;C); One-chip telephone ICs with speech, dialler and ringer functions
The ICs UBA2050, UBA2050A, UBA2051, UBA2051A and UBA2051C contain all the functions needed to build a fully electronic telephone
set.
In many places in the text, figures and tables, the description is not applicable for all the five types, but only for one or two or for a
combination. These combinations will be referred to by means of short denotations as given in Table 1.
Table 1 Denotations of types
The devices incorporate a speech/transmission part, a dialler part and a ringer part. By offering a wide range of possible adaptations for
each part, the UBA205xx applications can be easily adapted to meet different requirements.
Speech/transmission part
The speech/transmission part performs all transmission and line interface functions required in fully electronic telephone sets. It performs
electronic switching between transmission and dialling. The IC operates at a DC voltage down to 1.45 V (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 pin LN in order to create a supply point at pin VDD . The
