GENERAL DESCRIPTION
The TEA1098A is an analog bipolar circuit dedicated for
telephonyapplications. Itincludes aline interface, handset
(HS) microphone and earpiece amplifiers, handsfree (HF)
microphone and loudspeaker amplifiers and a duplex
controllerwithsignalandnoisemonitorsonbothchannels.
Digital volume control is available both on earphone and
loudspeaker amplifiers.
This IC provides a 3.35 V strong supply for a
microcontroller and a 2.0 V filtered voltage supply for an
electret microphone.
