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
(-law or A-Law) mode, which is selectable through the I2C 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 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.
