DESCRIPTION
The voice-band audio processor (VBAP) is designed to perform transmit encoding analog/digital (A/D) conversion, receive
decoding digital/analog (D/A) conversion, and transmit and receive filtering for voice-band communications systems. The
device operates in either the 15-bit linear or 8-bit companded (u-law or A-Law) mode, which is selectable through the I2C
interface. The VBAP 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.
