TLV320AIC14CDBTR

Codecs Overview

The TLV320AIC14CDBTR is a low-power, highly integrated mono 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 voltage of 1.65 V to 1.95 V, digital I/O from 1.1 V to 3.6 V, and an analog supply of 2.7 V to 3.6 V. The component is housed in a TSSOP-30 package and is characterized for industrial operation between -40°C and 85°C.

Codecs Feature Summary

• Integrates programmable gain amplifiers, microphone preamplifiers, and selectable FIR/IIR filters for voice-band applications.
• Supports glueless interface to DSPs via SMARTDM serial port and flexible host control through I2C or S2C interfaces.
• Includes power management modes allowing independent shutdown of ADC, DAC, and operational amplifiers.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• VOIP systems

Codecs Procurement Notes

Verify the specific ordering suffix 'C' indicates commercial temperature range (0°C to 70°C) while 'I' denotes industrial (-40°C to 85°C). Confirm the 'DBTR' suffix corresponds to the TSSOP-30 package with tape and reel packaging containing 3000 units. Ensure compatibility with system voltage requirements before procurement.

Codecs Selection Notes

Select this model for mono voice applications requiring low power consumption and high integration. The TLV320AIC14 variant lacks the speaker driver found in the AIC12K series, making it suitable for external amplifier designs. Verify that the required sampling rate and filter characteristics align with the system's audio processing needs.

Codecs Part Context

This component belongs to the TLV320AIC1x family of audio codecs. It shares architectural similarities with the TLV320AIC12, AIC13, and AIC15 models but differs in specific output capabilities and package options. The 'K' variants within this family offer enhanced clocking flexibility for cascaded operations.

Codecs Replacement Considerations

Public confirmed substitute part numbers include TLV320AIC14IDBTR for industrial temperature range and TLV320AIC14CDBT for smaller tape and reel quantities. Direct pin-compatible replacements within the same package are limited to other members of the AIC1x series.
