TLV320AIC12IDBT

Codecs Overview

The TLV320AIC12IDBT 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 voltage of 1.65 V to 1.95 V, digital I/O voltage of 1.1 V to 3.6 V, and analog supply voltage of 2.7 V to 3.6 V. The component is housed in a TSSOP-30 package and is characterized for industrial operation from -40°C to +85°C.

Codecs Feature Summary

• Integrates programmable gain amplifiers, microphone preamplifiers, handset/headset amplifiers, and selectable FIR/IIR filters for complete voice-band signal conditioning.
• Supports Smart Time Division Multiplexed (SMARTDM) serial interface for glueless connection to DSPs and microcontrollers, allowing cascading of up to 16 devices.
• Includes flexible host port compatible with I2C or S2C protocols for register configuration and power management control.

Codecs Applications

• Wireless accessories
• Hands-free car kits
• VOIP systems
• Speech processing applications

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 'I' designator matches the required operating environment for your application. Check the latest Package Option Addendum on the manufacturer's website for current availability and tape/reel quantities associated with this specific part number variant.

Codecs Selection Notes

Select this component for mono voice-band applications requiring low power consumption and high integration. Ensure the system architecture utilizes the SMARTDM interface or requires the specific cascade capabilities offered by this series. Verify that the available analog outputs meet the load requirements, noting that the standard AIC12 lacks the speaker driver found in the AIC12K variant.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-power mono codecs. The 'I' suffix denotes the industrial temperature grade, distinguishing it from the commercial grade 'C' variant which operates from 0°C to 70°C. The DBT suffix indicates the TSSOP-30 surface-mount package. This family is designed for compatibility with Texas Instruments TMS320 DSPs.

Codecs Replacement Considerations

TLV320AIC12CDBT: Commercial temperature grade version (0°C to 70°C). TLV320AIC12KIDBT: Variant with integrated 8-ohm speaker driver. TLV320AIC13IDBT: Similar mono codec with different amplifier configurations.
