DESCRIPTION
The TLV320AIC1107 PCM codec is designed to
perform the transmit encoding analog-to-digital (A/D)
conversion, the receive decoding digital-to-analog
(D/A) conversion, and the transmit and receive filtering
for voice-band communications systems. The
TLV320AIC1107 device operates in either the 13-bit
linear or 8-bit companded (A-law) mode. The PCM
codec generates its own internal clocks from a
2.048-MHz master clock input.

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.
All other trademarks are the products of their respective owners.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
