PCM CODEC  
FEATURES  
DESCRIPTION  
D
2.7-V Operation  
The PCM codec is designed to perform the transmit  
encoding analog/digital (A/D) conversion and receive  
decoding digital/analog (D/A) conversion, together with  
transmit and receive filtering, for voice-band  
communications systems. The device operates in  
either the 15-bit linear or 8-bit companded (µ-law or  
A-Law) mode, which is selectable through the I C  
interface. From a 2.048-MHz master clock input, the  
PCM codec generates its own internal clocks.  
D
Two Differential Microphone Inputs, One  
Differential Earphone Output, and One  
Single-Ended Earphone Output

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 V  
or ground. Specific guidelines for handling devices of this type are contained in the publication Guidelines for  
CC  
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.  
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.
