TLV320AIC12CDBT

Codecs Overview

The TLV320AIC12CDBT 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-digital converter. The device supports a maximum sampling rate of 26 ksps with on-chip filters or up to 104 ksps when bypassed. It operates within a digital core 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 is housed in a TSSOP-30 package and is characterized for commercial operation from 0°C to 70°C.

Codecs Feature Summary

• Integrates programmable gain amplifiers, microphone preamplifiers, handset amplifiers, headset amplifiers, and selectable FIR/IIR filters for comprehensive voice-band signal processing.
• Supports glueless interface to DSPs via SMARTDM serial port and flexible host port compatible with I2C or S2C protocols.
• Includes extensive power management capabilities allowing independent software control for ADC, DAC, operational amplifiers, and filters to maximize system power conservation.

Codecs Applications

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

Codecs Procurement Notes

Verify the specific ordering suffix 'C' confirms the commercial temperature range (0°C to 70°C) and the 'DBT' suffix indicates the TSSOP-30 package. Confirm the document revision status matches current production data requirements. Ensure compatibility with the intended digital I/O voltage levels before finalizing procurement specifications.

Codecs Selection Notes

Select this component for mono voice applications requiring low power consumption and high integration. Verify that the commercial temperature range meets the environmental requirements of the target application. Ensure the system design accommodates the specific analog and digital supply voltage ranges defined in the datasheet.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-power audio codecs. It shares functional similarities with the TLV320AIC13, TLV320AIC14, and TLV320AIC15, differing primarily in output driver capabilities and temperature ratings. The CDBT variant specifically denotes the commercial grade version in the TSSOP-30 package.

Codecs Replacement Considerations

TLV320AIC13CDBT offers similar functionality but may have different output driver specifications. TLV320AIC12KIDBTR provides industrial temperature rating and includes an 8-ohm speaker driver, requiring circuit redesign for pinout and power supply differences.
