TLV320AIC14KIDBT

Codecs Overview

The TLV320AIC14KIDBT is a low-power, highly integrated mono audio codec manufactured by Texas Instruments. It features a 16-bit oversampling sigma-delta analog-to-digital converter and a matching digital-to-analog converter. The device supports a maximum sampling rate of 26 kSPS with on-chip filters or up to 104 kSPS when filters are 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 performance metrics include an 84 dB signal-to-noise ratio for the ADC and 92 dB for the DAC. The component utilizes SMARTDM serial interface technology and includes programmable gain amplifiers, microphone preamplifiers, and selectable FIR/IIR filters.

Codecs Feature Summary

• Includes built-in analog functions such as MIC preamplifier, handset amplifier, and headset amplifier.
• Supports flexible power management with independent software control for ADC, DAC, and filters.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• VOIP devices
• Cable modems
• Speech processing systems

Codecs Procurement Notes

Verify the specific ordering suffix IDBT corresponds to the TSSOP-30 package and industrial temperature range (-40°C to 85°C). Confirm that the K designation indicates the industrial grade variant within the TLV320AIC1x family. Ensure compatibility with the required host interface protocols before finalizing procurement specifications.

Codecs Selection Notes

Select this component for voice-band applications requiring low power consumption and high integration. It is suitable for designs needing a mono codec with programmable gain and internal filtering capabilities. Consider the available serial interfaces and power supply requirements when integrating with the target digital signal processor or microcontroller system.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-power audio codecs from Texas Instruments. The family includes variants like the TLV320AIC12, AIC13, AIC14, and AIC15, with the 'K' suffix denoting industrial temperature rating. These devices share common architectural features but differ in specific output drivers and package options.

Codecs Replacement Considerations

Direct replacements within the same family include the TLV320AIC14KIDBTR (tape and reel version) or the non-K industrial variant TLV320AIC14IDBT. Verify package pinout compatibility and thermal characteristics when substituting.
