TLV320AIC12CDBTR

Codecs Overview

The TLV320AIC12CDBTR is a low-power, highly integrated mono voice band 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 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. Power consumption is typically 11.2 mW at 3.3 V in standard operation. The component is housed in a TSSOP-30 package and is characterized for commercial temperature ranges from 0°C to 70°C.

Codecs Feature Summary

• Integrates a 16-bit mono ADC and DAC utilizing oversampling sigma-delta technology for high-resolution signal conversion.
• Includes programmable gain amplifiers, microphone preamplifier, handset amplifier, headset amplifier, and selectable FIR/IIR filters.
• Supports glueless interface to DSPs via SMARTDM serial port and flexible host port compatible with I2C or S2C protocols.
• Features extensive power management with independent software control for ADC, DAC, operational amplifiers, and filters.

Codecs Applications

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

Codecs Procurement Notes

Verify the specific ordering suffix 'CDBTR' corresponds to the commercial temperature range (0°C to 70°C) and the TSSOP-30 package configuration. Confirm that the tape and reel quantity matches the required production volume, as this suffix indicates a reel packaging format rather than cut tape or tube. Ensure compatibility with the intended operating voltage levels before finalizing procurement.

Codecs Selection Notes

Select this component for mono voice-band applications requiring low power consumption and high integration. It is suitable for designs needing a single-channel codec with built-in amplifiers and filters. Consider the commercial temperature range limitation if the application requires industrial-grade thermal performance. Verify that the available serial interfaces meet the system's connectivity 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 TLV320AIC12, AIC13, AIC14, and AIC15, which share similar core functionalities but may differ in package options or specific output driver capabilities. The 'C' designator indicates the commercial temperature grade, distinguishing it from the 'I' variant designed for industrial temperatures.

Codecs Replacement Considerations

The TLV320AIC12IDBTR serves as a direct replacement for industrial temperature range requirements (-40°C to 85°C). Other family members like the TLV320AIC13 or TLV320AIC14 offer pin-compatible alternatives within the same package, though feature sets may vary slightly.
