description

The TWL1106 voice-band audio processor (VBAP) is designed to perform transmit encoding analog-to-digital

(A/D) conversion, receive decoding digital-to-analog (D/A) conversion, and the transmit and receive filtering for

voice-band communications systems. The TWL1106 device operates in either the 13-bit linear or 8-bit

companded

(µ-law) mode. 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.

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.
