TLV320AIC12KIDBTR

Codecs Overview

The TLV320AIC12KIDBTR is a low-power, highly integrated mono voice codec manufactured by Texas Instruments. It features a 16-bit oversampling sigma-delta ADC and DAC with a maximum conversion rate of 26 kSPS. The device supports a master clock up to 100 MHz and operates on supply voltages ranging from 1.65 V to 1.95 V for the digital core, 1.1 V to 3.6 V for digital I/O, and 2.7 V to 3.6 V for analog sections. It includes an 8-ohm speaker driver, programmable gain amplifiers, and selectable FIR/IIR filters. 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 a mono 16-bit sigma-delta ADC and DAC with programmable sampling rates and internal anti-aliasing filters.
• Includes an 8-ohm speaker driver and dedicated handset/headset amplifiers for direct audio interface.
• Supports Smart Time Division Multiplexed (SMARTDM) serial port for glueless DSP interfacing and automatic cascade detection.
• Features extensive power management with independent software control for ADC, DAC, and amplifier sections.

Codecs Applications

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

Codecs Procurement Notes

Verify the specific ordering suffix IDBTR confirms the TSSOP-30 package and industrial temperature range (-40°C to +85°C). Confirm the K variant designation indicates the inclusion of the 8-ohm speaker driver functionality. Ensure compatibility with the required host processor interfaces, specifically SMARTDM or I2C/S2C control protocols, before finalizing procurement.

Codecs Selection Notes

Select this component for mono voice applications requiring low power consumption and integrated output drivers. The AIC12K variant is distinct from standard AIC12 models due to its built-in speaker driver capability. Consider the available FIR/IIR filter options if low group delay is critical for active control applications. Verify that the system voltage levels align with the specified 1.65 V to 3.6 V operating ranges.

Codecs Part Context

This part belongs to the TLV320AIC1x family of low-power audio codecs. The 'K' suffix denotes the specific variant equipped with an 8-ohm speaker driver, differentiating it from the AIC12 which lacks this output stage. The 'I' indicates the industrial temperature grade, while 'DBTR' specifies the TSSOP-30 surface-mount package and tape-and-reel shipping format.

Codecs Replacement Considerations

TLV320AIC12IDBTR serves as a functional substitute but lacks the integrated 8-ohm speaker driver found in the AIC12K variant. Designers must verify if external amplification is acceptable when substituting. Other family members like TLV320AIC13 or TLV320AIC14 offer similar interfaces but may differ in pinout or specific analog capabilities.
