TLV320AIC12CDBTRG4

Codecs Overview

The TLV320AIC12CDBTRG4 is a low-power, highly integrated mono voice band audio codec manufactured by Texas Instruments. It features one 16-bit oversampling sigma-delta analog-to-digital converter (ADC) and one 16-bit digital-to-analog converter (DAC). The device supports programmable sampling rates up to 26 ksps with internal filters or 104 ksps when bypassed. It operates on a 2.7 V to 3.6 V analog supply and a 1.65 V to 1.95 V digital core supply. Key specifications include an ADC signal-to-noise ratio of 84 dB and a DAC signal-to-noise ratio of 92 dB. The component utilizes SMARTDM serial interface and I2C/S2C host port for control.

Codecs Feature Summary

• Integrates mono 16-bit sigma-delta ADC and DAC with programmable gain amplifiers and selectable FIR/IIR filters.
• Supports glueless connection to DSPs via SMARTDM serial port and flexible two-wire host port configuration.
• Includes comprehensive power management modes allowing independent shutdown of ADC, DAC, and operational amplifiers.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• Voice over IP (VOIP) systems

Codecs Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature range and 'TR' denotes tape and reel packaging. Confirm RoHS compliance status through official manufacturer documentation as regulatory requirements may vary by production batch. Ensure the ordering part number matches the exact package type and temperature grade required for the design.

Codecs Selection Notes

Select this component for mono voice-band applications requiring low power consumption and high integration. Verify that the operating voltage ranges align with the system's analog and digital supply rails. Consider the available package options and temperature ratings to ensure compatibility with the target environment and manufacturing processes.

Codecs Part Context

This device belongs to the TLV320AIC1x family of low-power audio codecs from Texas Instruments. The family includes variants such as the TLV320AIC12, TLV320AIC13, TLV320AIC14, and TLV320AIC15, which share similar core functionalities but may differ in specific output drivers or package configurations.

Codecs Replacement Considerations

Direct replacements within the same family include TLV320AIC12CDBT and TLV320AIC13CDBT. Verify pinout and register compatibility before substitution. Other family members like TLV320AIC14 or TLV320AIC15 may require schematic adjustments due to different driver capabilities.
