TLV320AIC12KIDBTG4

Codecs Overview

The TLV320AIC12KIDBTG4 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 enabled, or up to 104 ksps when the IIR/FIR filters are bypassed. It operates with a digital core supply voltage ranging from 1.65 V to 1.95 V, a digital I/O supply from 1.1 V to 3.6 V, and an analog supply from 2.7 V to 3.6 V. The component achieves a typical signal-to-noise ratio of 84 dB for the ADC and 92 dB for the DAC. It is housed in a 30-pin TSSOP package and is characterized for industrial operation between -40°C and +85°C.

Codecs Feature Summary

• Integrates an 8-ohm speaker driver alongside standard microphone, handset, and headset amplifiers for comprehensive audio handling.
• Supports flexible serial communication through Smart Time Division Multiplexed (SMARTDM) ports and a programmable two-wire host interface compatible with I2C or S2C protocols.
• Includes selectable finite impulse response (FIR) and infinite impulse response (IIR) filters to optimize signal processing for specific voice band applications.

Codecs Applications

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

Codecs Procurement Notes

Verify the complete part number against the manufacturer's current database to ensure availability and correct revision status. Confirm that the ordering suffix matches the required temperature range and packaging specifications. Cross-reference the datasheet version to validate electrical characteristics before finalizing procurement orders.

Codecs Selection Notes

Select this component for mono voice-band applications requiring integrated power amplification. Ensure the system design accommodates the separate analog and digital supply voltage requirements. Verify compatibility with the host processor's serial interface standards, specifically SMARTDM or I2C/S2C configurations, during the initial architecture phase.

Codecs Part Context

This device belongs to the TLV320AIC1x family of low-power audio codecs. The 'K' designation indicates the inclusion of an internal speaker driver, distinguishing it from standard variants like the TLV320AIC12. The 'IDB' suffix specifies the industrial temperature range and TSSOP-30 package type, while 'TR' denotes tape and reel packaging.

Codecs Replacement Considerations

The TLV320AIC12KIDBT is a direct functional equivalent within the same series. Other members of the TLV320AIC1x family may serve as alternatives if the speaker driver feature is not required, though pinouts and power specifications should be verified.
