TLV320AIC12IDBTR

Codecs Overview

The TLV320AIC12IDBTR 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 and one 16-bit digital-to-analog converter. The device supports a maximum sampling rate of 26 ksps with on-chip filters or up to 104 ksps when bypassed. It operates with a digital core supply voltage range of 1.65 V to 1.95 V, a digital I/O range of 1.1 V to 3.6 V, and an analog supply range of 2.7 V to 3.6 V. The component achieves typical signal-to-noise ratios of 84 dB for the ADC and 92 dB for the DAC. It is housed in a 30-pin TSSOP package.

Codecs Feature Summary

• Integrates programmable gain amplifiers, microphone preamplifiers, handset amplifiers, and headset amplifiers for comprehensive voice signal conditioning.
• Supports Smart Time Division Multiplexed (SMARTDM) serial interface for glueless connection to DSPs and microcontrollers.
• Includes selectable FIR/IIR digital filters and an antialiasing filter to optimize voice band performance.
• Provides extensive power management capabilities with independent software control for ADC, DAC, and operational amplifiers.

Codecs Applications

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

Codecs Procurement Notes

Verify the specific ordering suffix IDBTR confirms the industrial temperature range (-40°C to 85°C) and tape-and-reel packaging format. Ensure compatibility with the required analog and digital supply voltages before finalizing procurement. Cross-reference the manufacturer's latest package option addendum to confirm pinout and mechanical dimensions match the design requirements.

Codecs Selection Notes

Select this component for mono voice applications requiring low power consumption and high integration. The TLV320AIC12K variant includes an 8-ohm speaker driver, whereas the standard TLV320AIC12 lacks this feature. Consider the SMARTDM interface if interfacing with Texas Instruments DSPs. Verify that the 26 ksps sampling rate meets the system bandwidth requirements.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-power audio codecs from Texas Instruments. The family includes variants such as the TLV320AIC13, TLV320AIC14, and TLV320AIC15, which share similar architectures but may differ in output drivers or package options. The 'K' suffix variants, like the TLV320AIC12K, integrate additional speaker driver capabilities not present in the standard AIC12 model.
