description

The voice-band audio processor (VBAP) 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 VBAP generates its own internal clocks.

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

Handling Electrostatic-Discharge-Sensitive (ESDS) Devices and Assemblies available from Texas Instruments.

VBAP is a trademark of Texas Instruments Incorporated.

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.
