Microcircuit IL9200AN, IL9200AD
(FUNCTIONAL EQUIVALENT OF HT9200A HOLTEK)
is generator DTMF of signals. The IC is
purposed for formation standard DTMF the
signals used for frequency coding of dialed
number. It is used in telecom systems, consumer
electronic devices.
Performed function – generation of
standard DTMF signals and component
frequencies. It is recommended to use ILA9170,
ILA9270 for decoding of DTMF signals generated
by IC IL9200A.
The microcircuit is available in 8-pin DIP-
case MS-001BA and SO-case MS-012AA.
