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).
This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields. These
circuits have been qualified to protect this device against electrostatic discharges (ESD) of up to 2 kV according to MIL-STD-883C,
Method 3015; however, it is advised that precautions be taken to avoid application of any voltage higher than maximum-rated
voltages to these high-impedance circuits. During storage or handling, the device leads should be shorted together or the device
should be placed in conductive foam. In a circuit, unused inputs should always be connected to an appropriated logic voltage level,
preferably either VCC or ground. Specific guidelines for handling devices of this type are contained in the publication Guidelines for
Handling Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies available from Texas Instruments.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
†These _{options are available on some devices. Please see the table of comparison for the last two generations of PCM codecs.}
