APPLICATIONS

DESCRIPTION

The TLV320AIC1110 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

TLV320AIC1110 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 31.25 Hz through

the interface control. The analog switch provides more

control capabilities for voice-band audio processor

(PCM codec).

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.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
