Communication ICs
DTMF receiver for telephones
BU8871F
The BU8871F is a DTMF receiver ICs developed for use in telephone answering machines, and converts 16 different
types of DTMF signals into 4-bit binary serial data. It features a wide dynamic range, eliminating the need for an external
input amplifier. Expertise from a number of companies has been incorporated into these products to enable guard time
control through a host microcomputer.
FApplications
Telephone answering machines
FFeatures
1) Dynamic range of 45dB. (internal AGC)
2) 4-bit binary serial data output.
3) Guard time can be controlled through host microcon-
troller.
