Description
The TLV320AIC1110 provides extended gain and
attenuation flexibility for transmit, receive, and sidetone
paths. A differential earphone output is capable of
driving speaker loads as low as 8 for use in speaker
phone applications. The single tone function on the
TLV320AIC1110 generates a single tone output of up to
8 kHz. The resolution of the DTMF tone is also
selectable to 7.8125 Hz, 15.625 Hz, or 31.25 Hz through
the interface control. The analog switch provides more
control capabilities for voice-band audio processor
(PCM codec).
