Speech network for telephones
BA8216
The BA8216 is a speech network IC which possesses the basic functions required for handset communications. In addi-
tion to amplifying signals from a transmitter and sending them to a telephone line, it also amplifies only reception signals
from a telephone line and drives the receiver.
FApplications
Telephones and telephone equipment
FFeatures
1) Basic speech network functions built in.
S Handset transmit and receive circuits
S DTMF transmit circuit
S Key tone input circuit
S Mute control and side tone masking circuits
2) Can be used with 1.3kΩ loop circuit resistance and
100Ω telephone resistance.
3) A BTL circuit is used for reception output, providing
a wide dynamic range which enables use of a ceram-
ic receiver.
4) Few external components required.
5) 14-pin DIP package.
