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 Ω 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).
