description

The TWL1110 provides extended gain and attenuation flexibility for transmit, receive, and sidetone paths. A

differential earphone output is capable of driving speaker loads as low as 8 Ω for use in speaker phone

applications. The single tone function on the TWL1110 generates a single tone output of up to 8 kHz. The

resolution of the DTMF tone is also selectable to 7.8125 Hz, 15.625 Hz, or 31.250 Hz through the interface

control. The analog switch provides more control capabilities for voice-band audio processor (VBAP).

The VBAP is an analog-digital interface for voice band signals designed with a combination of coders and

decoders (codecs) and filters. It is a low-power device with companding options and programming features, and

it meets the requirements for communication systems, including the cellular phone. 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.

A coder, an analog-to-digital converter or ADC, digitizes the analog voice signal, and a decoder, an

digital-to-analog converter or DAC, analogs the digital-voice signal. VBAP provides a companding option to

overcome the bandwidth limitations of telephone networks without degradation in sound quality. The human

auditory system is a logarithmic system in which high amplitude signals require less resolution than low

amplitude signals. Therefore, an 8-bit code word with nonuniform quantization (µ-law or A-law) has the same

quality as 13-bit linear coding. VBAP provides better digital code words by generating a 15-bit linear coding

option.

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.

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.

These options are available on some devices. Please see the table of comparison for the last two generations of VBAPs.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
