语音频带音频处理器

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.
