DESCRIPTION
The TWL1110 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 TWL1110 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 31.250 Hz through the interface control. The analog switch provides more control capabilities for
voice-band audio processor (VBAP).
The VBAP is an analog-digital interface for voice band signals designed with a combination of coders and decoders (codecs)
